Tire Size Issues

Tire Size: What Is Too Big?

by Van
(Killingworth, ct.)

I have a 2004 Volvo S60.


I know the proper tire size is 195/65 but I have a set of brand new snow tires 215/60.
I was wondering if these tires are too big for the car? What is the worst that could happen?


Editorial Comment:


Generally speaking, I can see you are on the right track about changing tire size because the rule of thumb in seeking an alternative size is to reduce one of the first two numbers in its size when the other number increases.

The reason is that you need to maintain the overall tire diameter about the same and since the second number is a percentage of the first used to calculate the sidewall height, this helps to compensate for any changes.

You didn't give us the rim diameter, (the third number in a tire's size) but you can use our Tire Size Calculator to compare the two sizes and estimate the effects which you could expect.

There is a possibility that the wider tires might result in some obstruction or rubbing so I always recommend a test fitting before making a commitment to a larger size.

Different sized tires on original rims

by Chris K.
(Norfolk, Va)

Changing tires/rims?

Changing tires/rims?


I currently have P265/70R16 on my 2000 toyota 4runner which came with the vehicle. A friend of mine has a new set of P265/70R17's will they fit on my rims?


Editorial Comment: 

Absolutely NOT!

Please don't even try to put a larger diameter tire on a smaller rim --in this case a 17 inch tire on a 16 inch rim.

No self-respecting tire professional would try because even the mounting of a larger tire on a smaller rim could be dangerous to the person doing the work. Even if it did work, you'd be running a serious risk that the tire would come off when it gets installed on the vehicle, or even worse at some time when it is travelling on the road.

There's a similar danger in mounting smaller diameter tires on larger rims, but the danger to the person doing the work is less because of the great difficult they would have in doing it.

Remember the last two numbers in the tire size is the rim diameter: P265/70R16 are 16 inch and P265/70R17 are 17 inch.

Just so there's no doubt about how I view this: Don't ever mount tires on rims which have a different diameter size!

Different sized tires on front and rear wheels

by Dennis
(Granite City, IL)

Different sized tires on front and back

Different sized tires on front and back

A friend of mine can not afford new tires for his car. I am going to try and help him get some good used ones. I have found some I can afford, however he now has p225-60-R16 on his car, and the ones I found are p225-50-R16. Will this make a difference? I don't want to buy them for him if they will not work.



Editorial Comment:  The situation you describe is not as extreme as you see in the lawnmower, but I've chosen this photo to illustrate that some vehicles are designed to operate with different sized tires (and wheels).

That being said, in the two tire sizes you mentioned, there is 22.5mm difference in the height of the tire sections, the 225/50 R16 being the lower of the two.

If you do mix tire sizes on a vehicle that was not designed for this, there could be some difference in handling, steering and performance because of the different wheel sizes, but the only way to really know if this is a critical difference would be to install the tires and do some test driving.

This might be more hassle, and even more costly and time consuming than just shopping around enough until you can put on tires which are the same size on all wheels.

If you're really wanting to help out your friend, would you feel comfortable in having him install tires which might cause him to have an accident because of the change in handling that he wasn't expecting, or prepared for, just to save a few bucks?

Tire Concerns: Correct tires size for a 5.5JX16 Rim

by Ramesh
(India)


Can I mount a 225mm wide tire on 5.5J x16 rim?


Editorial Comment:

Generally speaking the width range of tires that will fit on any specific rim depends on the tire manufacturer and the ideal rim for which a tire is designed.

It is possible that a tire made by one manufacturer of a certain size is designed to be used on a different sized rim that the same sized tire made by another, but usually sizes are quite standard.

In the case of tires which are 225 mm wide I am not aware of any tire which might be used on a 5 1/2J rim. According to the data I have recently checked the largest tire that is likely to fit on that rim could be a 215/80 R16. Any tire with a lower profile is going to require a wider rim.

Tire Concerns: Best tire size for my car rims?

by Sohail
(Salmiya, Kuwait, State of Kuwait)

New Wheels

New Wheels

I just bought set of rims 16 inch for my BMW E30 325i with the follwing details:

Front rims: 16*7
Rear rims: 16*8

What is the best tire size for these rims? Please reply me back before i buy tires.

PS: The car has been lowered.




Editorial Comment: 

It would be impossible to recommend an exact size for you but here are some things to keep in mind.

First. The tires should be designed to fit well on 7 or 8 inch wide rims. This may be the same sized tire, or you might wish to use a slightly wider tire on the rear because of the wider rim, providing the space in the wheel well will allow it.

Because your car has been lowered this may complicate the range of tires you could use since you likely have less room in the wheel wells.

I would encourage you to find a dealer who will try some tires on to see how they fit (and look) before you make a purchase.

Tire Concerns: Using 185/65 R15 tires in place of 195/65 15 tires

by Ben
(Lake Sunapee, NH, USA)

varied tire sizes

varied tire sizes

I have been given brand new 185/65 r15 tires but my car has 195/65 r15 on it now and I wonder if the new tires are ok to use.


Editorial Comment: 
There are usually two issues to consider when you think about changing tire sizes, in a case like yours.

First is the wheel size. In your case both tires are designed for use on 15" wheels, as you can see from the sizes, so you are already on solid ground. Since the width of the tires (185 and 195) are only 10mm (or about 1/2 inch) different you're not likely to need a wider wheel, which could happen if you were thinking of changing from say a 195 tire to a 250 or something like that.

The second issue is the outside diameter of the tires as realted to the space in your vehicle's wheel well and clearance. In your case the small difference in the width and the same aspect ratio means that you have a minimal difference in the outside diameter of the different tire. The 185's are only 65% of 10mm smaller which is about 1/4 of an inch smaller than the original tires. This is not likely to create much of a difference.

So, in short -- go for it!

Tire Concerns: Tire width

by Rebecca
(USA)

Toyota

Toyota

I have a 2008 Toyota Camry (standard) with a tire size of P215/60R16. Am I able to put P225/60R16 tires on this car? What effect will a wider tire have on the vehicle?




Editorial Comment:

It is very likely that you can use the 225 tire in place of the 215 with practically no notable effect on your vehicle, its performance or handling.

The new tire you're considering is less than 1/2" wider and only 1/4" higher than the original, but even with this little difference, it is a good idea to try-on the other tire and see if there is any problem in terms of space where the tire might rub or be obstructed by some part of the vehicle in the wheel well.

Also, it doesn't hurt to ask a couple of tire dealers if they've had any experiences with this larger tire. Who knows, what you might discover by asking around?

By the way, you might be interested in knowing that your car is also sold as the Daihatsu Altis in some countries. (Just a bit of car trivia, I felt like passing on.)

Tire concerns: Installing oversized rims on a Hyundai Elantra

by Cory
(NB)

Vehicle with oversized 40 inch rims

Vehicle with oversized 40 inch rims

Can I put 16 inch rims on a 2004 Hyundai Elantra which has 15 inch rims as standard?

What you are thinking of may be covered in Plus Sizing which is the practice of changing the wheel size but maintaining the outside diameter of the tire.

The only obstacle you face in this case is to find a wheel where the bolt pattern matches the ones on your vehicle.

If you want to go beyond plus sizing, maybe even to the extreme in the picture above, then you need to start thinking about modifications to your vehicle to allow for the extra space which the new tires and rims are going to need.

Tire Concerns: What tire sizes can replace 30x9.50 r15 tires?

by Dena Forrester
(Jacksonville, Florida)


I have a 1998 Toyota 4 Runner.

4 new tires 2 years ago, the size 30x9.50 r15. One tire has nail in sidewall. Need new tire.

They are telling me that these tires are not sized right for my car and the replacement tire is no longer made by BF Goodrich in that size.

What do I do? Buy only one tire for $159 or buy 4.

Oh the spare is the old size - 225/75 r15. Great!

By the way, I bought these tires at Keith Pierson Toyota. Are they sized correctly for my car and are they safe to keep? Should I buy 2 and use one as spare? Please help.


Editorial Comment:
In theory the closest size to your original tire is 255/75 R15. A 265/75 R15 would likely work well too, but it would be a bit more than 1/2 inch larger in diameter than your 30x9.50 tire which is 30" in diameter and 9.5 inches wide.

Possibly the size you had is no longer made by BF Goodrich but you may find it made by another tire manufacturer.

Check on the door post on the drivers side or on the lid of your glove compartment door for a sticker from the manufacturer of the vehicle specifying what were the original tire size, if you have doubts about what is best for your vehicle.

You are much better off switching to another tire company rather than mixing tire sizes, especially on a 4WD vehicle.

If you've had no problems with the tires you now have, there's no logical reason to change to another size, providing you like the way they handle and look.

The smaller sized spare is of some concern. Your best bet would be to buy 2 tires and mount them on your car and use one of the older tires for the spare.

Depending on where on the sidewall your damage was, it might be possible to repair it and then to use that tire as your spare if it can be fixed, using it only for emergency use.

Tire and Wheel Compatability

by RR
(ID)

1995 Pontiac Firebird

1995 Pontiac Firebird

People often ask questions like: " I have a 95 Firebird which uses 225/60 R16 tires. I'd like to put 225/55 R16 tires on the rear axle. What can I expect and will the tire fit on the 16" original aluminum wheel?"

In part, this is a subject that is covered in the article on Plus Sizing, even though there's no "plus" involved here. You're considering a Plus 0 change, and in reality are considering a tire just slightly smaller than what you started with.

The /55 or /60 is called the aspect ration and us use it as a percentage of the first number 225 to calculate the height of the tire's section, measured from the rim to the tread of the tire.

In this case, you're looking at lowering the height of the tire by about 11 millimeters from 135 to 123. This is less than 1/2 an inch, so the effect on your car's ride, performance, etc. is very likely to be almost nothing.

As for fitting on the original factory wheel, you're still using the same diamerter tire (R16) and the width of the tire is still the same (225) so unless the tire manufacturer recommends a different WIDTH of wheel from the one you have, you shouldn't have any problem. The chance of this is so low (based on the tires involved) that I wouldn't even bother to check, but if you really want to be sure, then get your tire dealer to check what size of wheel is recommended for this tire.

Since the Firebird is a 2 wheel drive vehicle, there's no problem in putting different sized tires on the rear axle, but this is NOT recommended if you have a 4X4 or all-wheel drive. Different sized tires, on these vehicles, can lead to serious problems.

Another article which might come in useful is the one on Sidewall markings which explains what you can learn from what is written on the tire's sidewall.

Plus sizing tires

by Krystle
(Texas)

Toyota Corolla LE  --a candidate for Plus Sizing?

Toyota Corolla LE --a candidate for Plus Sizing?

I own a 2004 Toyota Corolla LE.

I would like to put 17 inch wheels and tires on it. I have been doing research and I have found something called plus sizing. My question is if I put a 225/45 R17 tire on 17 x 7 inch wheels, would they work? I already have 15 inch wheels on 195/65 R15 inch tires.

I really would like to put a larger wheel to make my vehicle look better.


Krystle,

Plus Sizing seems to work for you.

In terms of outside diameter the switch seems to make sense and would cause no problems with speedometer accuracy or other issues.

One problem that might come up is with the width the the tire which might result in some difficulty depending on the space in your wheel wells. If you can arrange to try out a wheel and tire before committing to a purchase you can find out beforehand whether this would be an obstacle in your case.

Tire concerns: Using 225 55R/16 instead of 205 55R/16 tires

by Argie
(Canada)


"fat" tire

I bought 2 sets of 205 55R/16 tires (winters and V rated summer tires) for my a 2005 Lincoln LS

I have a 2005 Volvo S60 2.5T which comes loaded from the factory with 205 55R/16.

My question: since I would not use the Lincoln in the winter, could I safely replace the 205 55R/16 on my Volvo with the 225 55R/16 from my Lincoln ?

Any information that will help me understand a little more about tires sizes and its safe application.


Editorial Comment: 

Unless you made a typo in describing your tire sizes, there are two issues at stake here:

First is the considerable extra width of the 225 tire over the 205 tire. There is a possibility that a wider tire might not work well in another vehicle because of lack of space in the wheel wells and possible rubbing when turns are made.

The other issue is the size, or width, of the rims on which the tires would be used. It is possible that the 225 tire might require a wider rim than you were using for the 205 tire. You'd be wise to check on the rim requirements that the tire maker has for that specific 225 tire and see if the rim on which you would use it is within the range which the tire was designed to fit.

205 or 215 R55 Which tire size represents more rubber?

by K.C
(Milwaukee, WI,U.S)

Typical tire size

Typical tire size

I would like to know what these digits represent example 205 R55,215 R55, 225 R65.

KC, when you compare the numbers you've shown with the ones in the photo, you may note that you've left off some parts.

Let's start with your "205". It would be equivalent to the "245" in the tire size shown above. This is the width of the tire, measured in millimeters. Since 1 inch is 25.4 mm, the tire in the picture is just under 10" wide, a 205 would be about 8".

Following the first three digits is /70. This means 70% and if you multiply the first number, 245, by .7, you can calculate the height of the tire. This tire has a height of 171.5 mm.

To find out how much rubber a tire contains, you'd need to know the second number too because a short 255 tire might contain less rubber than a tall 205, but if the case were reversed and you had a short 205 wide tire, or even one which was the same width, the 255 tire would likely have more rubber in it.

The number after the width (R16) represents the size of the wheel rim. This also would influence the amount of rubber in a tire, because a tire on a 16 inch rim, for example, would have more than another tire which had a 15 inch rim.

Even if you had all the numbers, it still might be possible to exactly determine the tire size which contained the most rubber, because one tire might be manufactured using different components than another ... but with all the numbers, you could get an idea.

If you want more information about the information on a tire's sidewall (tire size, treadwear, DOT code, etc), see Tire Markings. which covers this.

Tire Concerns: changing tire size

by Gary Ledge
(Australia)

Currently, my tire size is 185/60R15 on steel wheels (rims)5.5j in size.
Is it ok if I change the tire into 195/55/R15 on the same set of rims? I have already calculated all the factors and the bottom line is. The 195 is .7mm smaller in diameter compare from the original tire size.

A change of this size should not produce any problems, but I always like to try on a new size before making a final decision to ensure that there are no issues. TG

Tire Concerns: Understanding Tire Sizes

by Mary
(Iowa)

Making sense of tire sizes

Making sense of tire sizes

I do have 4- P65/65R17 tires and I found 4- P65/70R17 on sale my question is can I still replace my tires with these tires? I don't know if these tires will fit my rims properly or not since they have different numbers and I don't know what they mean.


Editorial Comment:  You'll find a complete explanation of how to read a tire sidewall at
Tire Markings.

Briefly, though, the first number tells you the width of a tire in millimeters, the next number is a percentage to calculate the height of the tire section and the last number is the diameter of the rim, or wheel, on which the tire is to be used.

In the case you've given the the first number (P65) on both tires doesn't seem right ... it's likely P165, or possibly 265, but in any case, the second tire is just slightly higher than the first one, but the difference is less than 1/2 an inch, so you're not likely to face any problems switching from one to the other.

Effect of changing 16 inch tires for 17 inch Tires

by Greg
(Schaumburg IL)


My friend suggests that on her Chevy pickup her 16" tires were replaced with 17" tires on the same rims.

She pulls a 30 foot RV. She is wondering if this tire difference makes a difference in the truck's turning radius.


Recently, when backing the RV into a parking spot at a local campgound she had difficulty in doing the manouver which she had done previously without trouble. Having done this before she can't find any other reason for not "hitting the spot" dead on.

Can you shed light on this?

Up Sizing Tires

by John Z.
(PGH)



I am in the process of purchasing 4 all season radial tires for my 2005 Nissan Sentra. The tire which is on the car presently is a 195 55 r16. This tire is pretty expensive, I feel, for the type of driving I do plus it’s tough to get an all season radial at a descent price.

Upon reading and calling different places some places say I can “size up” With no problem but others say I shouldn’t.

The size they recommend is a 205 55 r16 which is more common and less expensive.

Is this a feasible solution or am I asking for trouble and if I buy this size will it effect anything on my car


Editorial Comment:  What you're contemplating is known quite broadly as Plus Sizing and I recommend you read our article on it.

Specifically you're contemplating a Plus-Zero change, in which the diameter of the wheel does not change, but the width of the tire does.

The major precaution to take in this case is to ensure that there is no rubbing in the wheel-well produced by the wider wheel.

Generally, if you say within the bounds in the Plus-sizing system, you're not likely to find any issues which will affect the performance of your vehicle in a way that should worry you.

Tire Concerns: Changing Rim Size

by Jack
(Ottawa, Canada)

extreme tire!

extreme tire!

I have an 09 Honda Accord EX-L with 225/55R17 stock tires. Can I change to 16" rims? I'd like to use my 16" alloys with 215/65R16 winter tires. What do you think?



Editorial Comment:

What you're thinking of doing is a kind of plus-sizing in reverse.

Instead of increasing your rim size you're wanting to decrease it, but the ideal situation is to keep the outside circumference of your new tire the same as what you started with so that there is no change in performance, speedometer reading or fuel consumption because of the change.

If you read the page I've linked to above and use the plus-sizing calculator that is available you need to work at it backwards to find the equivalent tire. In stead of putting in your existing tire, enter in the smaller rimmed tire size and do a plus 1 sizing, progressively changing the width of the tire until you see your original tire in one of the results boxes.

I've done this for you and the closest match for your 17 inch standard tire is a 210/65R16 tire, not the 215/65R16 you're considering which will result in a slightly larger diameter tire

Tire Concerns: Plus sizing wheels

I have a Camary with ugly 15 inch wheels and hub caps sized 205/65R15. I would like to replace them with 16 inch wheels tires such as 205/55R16. How would that work?



Editorial Comment:

You're thinking of doing what is commonly called Plus Sizing in the tire world.

Check out the link to get more details. In your case the closest theoretical sizes would be 220/55R16 or 200/60R16 to maintain the same outside diameter.

These sizes may not be available and you'll then have to choose something from what is available but with a slight change in diameter.

Try a 215/55 which is just slightly shorter or a 205/60 which will be just slightly taller, but either probably will be within a tolerance which would be acceptable.

Tire concerns: replacing P215/60R16 tire with P225/60r16

by JH
(Eaton, Ohio)

Ford Taurus

Ford Taurus

I currently have a 2003 Ford Taurus with factory rims. The tires which are worn out are p215/60r/16 and I am thinking of replacing those tires with P225/60R16 tires. Is this possible and what are the consequences?



Editorial Comment:

Changing from P215/60R16 tires with P225/60r16 tires is probably not a major issue.

To start with the difference in height of these two tires is just 6mm. (This is 60% --the aspect ratio of each-- of the difference in width which is 10mm). This means that the overall tire diameter will increase by 12mm and this works out to be about 1.4% of the original tire size.

This is the percentage difference you can expect in power, speedometer reading and fuel consumption...which isn't a great issue.

Aside from that unless you have been using rims which are not designed for 215/60R16 tires, this change will likely be within the specs for the existing rims, and the difference of having a tire which is 6mm higher than before is not likely to lead to a space problem inside the wheel well.

So, if this change is what you want ... go for it!

Tire Concerns: Variation from specified tire size

by Karen
(Raleigh)

sample tire sizes

sample tire sizes

My car is supposed to have 225/55/r16's as it does now, but I need to replace them and I was told I can put 225/60/r16's on there ...is this true?


Editorial Comment:

In theory there are several different alternatives which will work when you want to change to a different tire size on your car.

One approach is a concept called Plus Sizing in which the entire object is to maintain the exact same overall tire diameter even though you may increase (or decrease) the size of the wheel.

Another approach is to actually increase or decrease either the tire height or width within the constraints of the space available for the wheel and tire. In some cases there may be an effect on the power, performance, speed, fuel consumption, etc to consider ... in other cases the effect would be minimal.

In your case, it seems to me that the effects on car performance would be minimal, but in the tire sizes you mention you are considering a slightly larger tire which is about 11 mm (or about 1/2 inch) higher that the original.

Tire Concerns: Will a P225/60R16 Tire fit an 8" wide rim?


I have a rear wheel drive 1999 Pontiac Trans Am that I am driving in the winter. I want to mount studded snow tires on it that are P225/60R16. The Alloy rims are 8 inches wide, the snow tires are currently mounted on Ford rims that are 6.5 inches wide. The rest of the Trans Am tires are currently P235/55R16, car originally came with P245/50ZR16.

My concern is simply, will the narrower snow tire fit the 8" wide rim, or will it be too narrow to reach the bead sealing surface and "fall in" to the center of the rim?



Editorial Comment:

Industry standards say that a 225/60 tire should be used on a 6 1/2J, or 7J Rim.

Permitted rims are 6J. 7 1/2J and 8J

So it would seem that you are at the upper limit of the Permitted category.

Since I don't know your driving habits and road conditions I am reluctant to give you a strong OK, but if you are not going to be pushing your vehicle to it's peak performance and are carefully controlling your tire pressure, then I'd say you're not likely to experience any problems.

It is your responsibility to remember that you are pushing the limit with this choice.

Scooter Tire Sizing

by Tei
(Chicago, IL, USA)

1986 Volkswagen Scooter

1986 Volkswagen Scooter

How are Scooter Tires sized?

For example, if a 3.50-10 tire equals a 110/90-10 tire, then what is the equivalent of a 4.00-10 tire?

These are scooter tires for 50cc and larger scooters.




The short answer is that the equivalent to a 4.00-10 scooter tire is a 120/90 10 tire.

We're looking for more precise information, but for the moment we know the following:
4.00 is a measurement in inches, as is the 10, which is the wheel rim diameter.

In the other sizing method, if it is similar to car tires, the first number is a measurement in millimeters (probably the width) and the number with a slash (/90) is a percentage used to calculate the tire's height. The last number, is also in inches and is, the wheel diameter.

Tire Concerns: switch from 225/50 16 to 225/55 16 for increased clearance

by rollie antonio
(antioch, calif. usa)

Could I switch from 225/50 16 to 225/55 16 on the same rims for increased clearance?

With my current tires on 2003 Pontiac Grand Am GLT, there isn't enough ground clearance. The lower front splash guard rubs the the ground when backing up from driveway to the street. No modifications made, everything stock from the dealer.



Editorial Comment:

Probably for the amount you'd spend on changing tires to solve this problem, you might get better results spending the money on modifying your driveway so that there isn't such a sharp angle where it meets the street.

The change you propose would add about 1/2 inch height to your vehicle at the wheel ... it's not likely to help much.

Substituting 205/65 R15 tires for 215/65 R15

by Doug
(Canada)

typical Snow Tire

typical Snow Tire

Is there any concern with using 4 spare P205/65R15 snow tires that I have to replace the worn out p215/65R15 summer tires on an older Dodge Caravan?


Doug, TIRE GUY from Tire-Information-World.comthe switch means you'd be installing a tire which is slightly narrower (10mm) which is less than 1/2 inch, and a bit lower (65% of that), so --size wise it doesn't seem to be much of a problem for clearance. You may have to increase your tire pressure by an almost insignificant amount because of having a smaller tire, but really nothing to make much of an issue about (maybe 1/2 psi).

The biggest difference you may notice is the ride comfort and noise level, but if these don't bother you, go right ahead. Of course, I'm assuming the winter tires are in good shape, no sidewall cracking and even treadwear.

Tire Concerns: How does aspect ratio affect performance?

by Steve Riley
(Collingwood, Ontario Canada)

tire size showing aspect ratio

tire size showing aspect ratio

I have P215/65R15 all season tires on my 1998 Dodge Caravan.

I have a new set of P215/70R15 snow tires meaning the aspect ratio is slightly different. I think it is about 10 or 11 mm different.

Does that mean the tire is 20 - 22 mm taller ?

Will these still fit and what might I expect in terms of drive changes?



Editorial Comment:

You have the idea of the aspect ratio right, you multiply the ratio (which is the figure following the slash, and considered to be a percentage) by the first figure to calculate the height of the tire side wall.

Since there are two sidewalls you then need to double the result to determine the overall effect on the tire's diameter.

5% of 215 times two is 21.5 millimeters or just under 1 inch.

Usually a one-step change in Aspect Ratio (they always change in increments of 5), does not result in any significant change in vehicle performance, speedometer reading or fuel consumption. Yes, there is a change, but most people don't notice it because it is what they consider to be minimal.

A one step change in the ratio also does not usually cause any problems in terms of fitting within a vehicle's wheel well, however, if you have already been using tires which are not the standard size for your vehicle, you may experience some difficulty. In this case, I always recommend trying out the fit before committing to the purchase of a different size.

Tire Concerns: Effect of changing rim size

by arth
(philippines)

Will there be a significant difference if I change my rim and tire size for my 1st generation honda CRV which is currently 205/70/r15 to 215/65/r16 or 225/60/r16 or 235/60/r16. Which tire size could I use as the best replacement?



Editorial Comment:

What you`re considering is usually called Plus-sizing and you can find out all about it from Plus Sizing .

The basic aim of plus sizing is to maintain the same outside tire diameter so that you have no difference in performance or other issues.

Tire Concerns: Using smaller rims

by Stephen
(Texas)

I have a 2001 Ford Mustang with OEM 16 inch rims. The tires for this rim are much more expensive than if it had the 15 inch OEM rims on it. I found 15 inch rims on a 2001 Mustang in a salvage yard and everything seems to add up to me. However, is there some downside that I am not thinking about?



Editorial Comment:

What you are thinking of doing is rather common in the industry even though it may not be a wide spread thing.

To get more details on this you need to be looking at Plus Sizing but in reverse because instead of increasing your rim size you are going down.

As you astutely noticed, sometimes you can get tires which are considerably cheaper by changing a rim size, basically because the alternative tire size is probably more popular, more widely manufactured and more competitively priced.

If you do the Plus Sizing to a -1 (minus 1) your objective is to maintain the same tire diameter so you will have no performance changes or other issues. Just try to stay with a tire width which is fairly close to what you had on your original vehicle because if you don't you may have a problem with the space in your wheel well.

The likely "downside" is an aesthetic one ... some people don't like the looks of a higher profile tire which you will end up having to maintain the same tire diameter.

Tire Concerns: Low Profile Tires

by Robert
(Haralson County, GA)

Low profile tires

Low profile tires

I've been having a hard time finding the right tire for me because most tire companies tell me different things. I need the know what is one of the best tires to buy if you need low profile tires because right now I don't have a clue. I need a tire to last as long as possible.


Editorial Comment:

I think almost all of us agree that we'd like to have our tires last as long as possible, but it could be difficult to agree on what is the best tire for everybody, low profile, or otherwise.

In principle, being low profile should not have any effect on the life span of a tire, but there are other things that generally go together with low profiles that may affect the tire life.

In many cases, most low profile tires are also high performance tires, made with special compounds which improve their traction and handling characteristics. These compounds generally have proven to be softer and less durable than those used on standard tires, and they wear out faster. That's part of the price one pays for demanding better performance.

The treadwear code on a tire sidewall may help in getting the longest lasting tire available -- the higher the number, the longer you can expect the tire to last. A tire rated at 500 should be twice as durable as one rated at 250, but be careful in comparing the rating between different brands. The comparison is most valid when applied to tires made by the same manufacturer, because they all do their own testing, so inter-company comparisons may not be accurate.

See our article on treadwear for more details.

Once you've identified one or two tires which you feel you'd be inclined to buy, try doing a web search on those specific tires to read what kind of comments people may have made about them, then make your choice based on your own experience, driving habits and expectations.

Tire Concerns: Smaller Tire on Back of car.

by EDT
(USA)

Different tire sizes?

Different tire sizes?

My car tire size is currently P185/R65/14. I needed a new rear tire and so the mechanic shop replaced the one back tire with P185/R60/14. Will this affect my car in any way? If I have the shop replace it with the right size, would I be in need of an wheel alignment as well. Been driving like this for a week.



Editorial Comment:

The smaller tire under new conditions is a little less than 1/2" lower than the original tire in new condition.

If the other tires are considerably worn, this difference would be less and possibly almost not noticeable, especially if the pressure on the newer tire was increased a bit.

The increased pressure might compensate for the size difference but it would also make the new tire wear more rapidly.

The use of an odd sized tire should not cause an car which is properly aligned to require alignment, but it could result in handling difficulties and uneven wear.

For a short while, and depending on how much you drive, use of a slightly different sized tire shouldn't cause any mechanical problems, but the best course would be to put a properly sized tire on this wheel and --perhaps--keep this tire aa your spare, always with the idea of using it just in emergency situations until you have repair or replace a damaged tire.

Tire Concerns: Mounting R16 tires on R15 rims

by Harry
(Vermillion, SD 57069)

Audi A6 from 2008

Audi A6 from 2008

Can I replace an R15 tire with an R16 tire on my Audi A6. A Walmart salesperson said it was OK. I just purchased a set of R16 Douglas tires at Walmart for half off (on clearance).

The sales person stated that although it is against company (Walmart) policy for him to mount the tires, the tires work perfectly well without any compromise to performance or safety. He recommended having another shop mount the tires.

Is this correct information?

Tire Concerns: Effect of replacing P265/70/16 tires with P255/70/16

by Greg
(Gramercy, LA)

I have a 2005 Chevy Tahoe and it has P265/70/16 tires on it mounted on 8 inch wide rims and I am thinking about replacing them with a set of P255/70/16 Michelin Lattitude Touring tires as I can get a set of these at a savings of about 150 dollars.

The vehicle is strictly used on the highway and no towing is involved. What are the effects of such a change?



Editorial Comment:
The effects of this kind of change are minimal. Because you have a slightly smaller tire involved you may have to increase your inflation pressure slightly so as to not have your tires wear more on the shoulders than in the center of the tread.

Watch your wear patterns closely during the first couple of months to determine if you need to increase the pressure a bit. See wear problems for more details about this.

The new size is just slightly lower than the original and the vehicle will ride about 1/4" (7mm) lower, but since you're on highway this should be barely noticed, if at all.

Your speedometer will under-read slightly and your power transfer and fuel consumption will vary, but all of these will be minimal ... I'd guess you'd hardly notice it.

In the long run, however, the savings in tires will be probably be off set by a slight increase in your fuel consumption ... my calculations estimate that you'll have to use about 3% more fuel to cover the same mileage as your tires' life.

Tire Size Upgrade

by Elliott
(California)

Mazda Protege

Mazda Protege

I have a 2003 Mazda Protege ES. OEM tire size is 195/50/16. Would like to upgrade to 205/50/16.

Can this be done without tires rubbing?

Is this size OK to safely install on vehicle?


Editorial Comment:
In theory there should be no problem with the change you propose. There is a difference in total diameter of the tires of only 9mm, which is slightly more than 1/2 inch.

Some cars have very little space in their wheel wells which could affect a change and result in some rubbing, and it is best to try a larger tire before making a commitment, but to start with it doesn't look like there should be a problem.

Tire Concerns: Power effect of down sizing tires

by joe rose
(georgtown ky.)

Ford F150

Ford F150

I have a 2006 F/150 Ford with a 4.2 engine and a 3.31 rear and need more power. Will changing 17 inch to 16 inch increase towing power?



Editorial Comment:

To get an answer to this question you need to calculate the difference in the overall circumference of the tires you plan to use.

If you follow the normal practice of changing the tire height to compensate for the difference in the rim diameter you will end up with no difference at all, so that you're wasting your time and energy in even trying.

If you stay with exactly the same size of tire except for the rim size, for example going from a 225/60R17 to a 225/60R16 you will end up with a tire which is 1/17th or about 5.8% smaller. This will convert in the equivalent increase in power, a decrease in speedometer accuracy and fuel consumption.

There is a catch, though, which you may want to take into account: You will have a corresponding lower amount of ground clearance because of this change, which may have some effects you don't want.

Also, there may be some negative effect in the sense that if you are wishing to use the extra power to tow or haul a heavier load, this may have other effects on your vehicle's overall capacity and could have effects on suspension and other systems that are beyond the design capabilities.

Tire Concerns: Comparison of 225/75R16 with 245/55R16 tires

by Bryant
(Maryland)

BFG M/T Tire

BFG M/T Tire

I came across an opportunity to get 4 very good M/T tires at a good price. The issue is the tires are BFG M/T 225/75R16 and my stock tires are 245/55R16. The vehicle in question is a 2002 Mercury Mountaineer.

I know I'll be going to a narrower tire but I want to know is it possible?

What are some of the side effects I might face in terms of Safety, Comfort and Noise?

Also will the aggressive tread pattern compensate for the narrower profile in anyway?




Editorial Comment:
A "quick and dirty" way to compare tires of the same rim diameter with another is to simply multiply the first two numbers in the size together. If the numbers are about the same, then the outside diameter is the same and no great difference need be expected.

In this case the new MT tire is somewhat larger than the original. The actual difference is 34mm which is slightly more than an inch and the overall diameter is increased by more than 2 1/2 inches.

The first concern, in this case is whether there is enough space in the vehicle wheel wells to operate without rubbing or bumping on anything. In the end, a test fitting should be tried if you have any doubts.

Because of the increased diameter and circumference the new tire will cause an error in the speedometer reading, there will be a slight change in power transfer and in fuel consumption.

If you run the new tire at the same pressure as the previous one, you may find that the ride seems harder and this may end up having an effect on your shock absorbers and suspension system over the long run.

Because of the larger tread lugs, you'll likely find this tire more noisy on paved roads, but you'll have better traction in mud, snow and other off-road situations.

There may not be any significant safety issues with the possible exception of the MT tire possibly being rated for a speed lower than the original tire. MT tires are not usually rated for the higher speed ranges.

Tire Concerns: the effect of changing tire size.

by Andrew
(Monteral, Canada)

My question is about changing tire size from original size P185R65-15 to P205R60-15. On Toyota Carolla CE 2004 (no abs). The tire will fit the ride will improve. At what expense? How will this change impact the speedometer, automatic transmission and the computers on the car?



Editorial Comment:

When you change a tire's size you need to multiply the tire width by it's aspect ratio (the second number) to get the sidewall height. Double this to figure the tire diameter when you add in the rim diameter.

In this case the difference between the first tire and the second one is just 6 mm. When you consider that the original tire diameter was 621mm, a 6 mm increase is less than 1%.

A one-percent change in tire diameter is not going to make a significant difference in power, speedometer reading or fuel consumption. If you never did the calculations, you might not even perceive the difference.

Tire Concerns: Alternate tire size for VW Passat

by Doug
(Johnstown, NY)

2004 VW Passat

2004 VW Passat

I have a 2004 VW Passat. The car came equipped with P195 65R15 Michelin tires.

What should I consider if I wish to change tire sizes or brands for this vehicle?



Editorial Comment:

For any vehicle, the following may be considered.


  1. Usually the brand of tire that came as original equipment has little importance when replacing tires. The tire brand will have no effect on the performance or the warranty of the vehicle.


  2. Tires should be chosen with the road and driving conditions in mind, together with any personal preferences you might have for appearance. These may be different from what the manufacturer (or dealer) had in mind when the vehicle was sold new.


  3. To obtain the performance which the vehicle was designed to provide, the tire size should be the same as is recommended by the manufacturer. This is usually in a sticker posted on the driver's door or door post. This sticker will also provide the tire pressure which should be maintained.


  4. If you wish to change to a wider tire, which is shown in the first number of the tire size, reduce the aspect ratio (the second number) so that you get more or less the same number when you multiply the two numbers together. In the case of the 195/65R15, the closest match for a tire which has a width of 205 is the 205/60R15.

  5. If changing to a wider tire, it is a good idea to test fit the new tire to make certain that there will be no rubbing or obstruction because of the larger size inside the car's wheel well. Some vehicles, either by design or because of damage from an accident may have less space that could cause problems in using larger tires.



Rule of thumb: If you increase the width by 10, decrease the AR by 5. (This is because tire sizes are made in increments of 5, for both width and AR.)

Tire Concern: mounting a tire on a non-recommended rim

by Ramesh
(India)

Basic Tire Mounting

Basic Tire Mounting

I wanted to mount 225/75R16 tire on 5.5J rim, but the tire manufacturer recommends a rim size range of 6"-7". What could happen if I mount this on 0.5" smaller rim width?



Editorial Comment:

By going outside of the manufacturer's recommended rim width, you are inviting problems for yourself and possibly others.

If the manufacturer gives a range, usually the ideal --or best-- fit is to use a rim which is exactly in the middle of the range, or 6.5 inches in this case.

What happens when you use a rim narrower than the recommended one? First, the bead of the tires are pinched together so you may have the rim actually riding on a part of the tire not designed to fit against the rim, providing possible extra tire wear, and stress because of the pressure against the tire.

You may have to increase your tire pressure to compensate for the lesser air volume in the tire which may further exacerbate the problem mentioned above and increase the possibility that the tire may slip off of the rim either because of the air pressure, or because of side pressures when the tire is subjected to lateral stress when cornering, etc.

If using non-protected mounting equipment such as that shown in the photo, you may be exposing the person who mounts the tire to an increased risk of accidental death or injury which can happen if a tire comes off during the bead-seating part of the mounting process.

Tire Size for a 2000 firebird

by Jarren Casstevens

Peter Biondo's 2000 Pontiac Firebird

Peter Biondo's 2000 Pontiac Firebird

I have a 2000 Firebird and I was wondering what is the largest size tire I could put on it. Right now they have 215s. What is the biggest I could go?


Editorial Comment:  First, I think it is important to determine if you want to modify your car or not.


As you might guess in the photo above, that 2000 Firebird, seems to have tires much wider than the 215s which you mention. I would not be surprised if the rear wheelwells have been modified to accept those wider tires.


You did not mention the tire height which interests you, but unless you are prepared to make changes in your car, you are likely to be limited in this area too.


I hesitate to give you a specific tire dimension without seeing your vehicle in person. The best bet is to visit a tire shop and try tire and wheel combinations which appeal to you.

Tire concerns: Size difference of 215/65R17 and 225/50R17 tires

by jarod
(petersburg ny)

I have a set of Cooper snow tires 215/65r 17 and want to know if they will work on on my 2009 Accord The stock tires are 225/50R17.



Editorial Comment:

To determine the difference in size you need to compute the tires' height by multiplying the width by the aspect ratio.

The snow tires have a height of 139.75 mm (215 x 65%), and the stock tires have a height of 112.5 mm (225 x 50%). The difference is 27.25 mm which is over 1".

I'm not certain if the Honda Accord has enough space in all the wheel wells to allow more than an extra inch without rubbing or bumping when the larger tire is in use. If there seems to be lots of extra room when you look at your present tires, then you might want to test mount one tire in the area with the least amount of space to see if there is any problem.

Editorial Comment:

You may be pushing things a bit by going as far as you've described. I suggest you consult with someone who is in the business of selling wheels to determine the largest size that a specific wheel will support, since I don't have the specs at hand for 20" wheels. Those specs tell you what range of tires are acceptable for a given wheel.

You could look at the Tire & Wheel Packages at Tire Rack to see what they have available, then phone one of their people to ask for more specific details.

When you've got your new wheels, how about taking a photo and showing us at Tire Show Off ?

Tire Concerns: Changing aspect ratio in tire sizes

by Tony
(st louis Mo.)

If my car uses 215/55r16 size tires on it and I found somebody with 4 new tires cheap, which are
size p215/65r16 can I put them on my car without any problems?



Editorial Comment:

Notice the second pair of numbers in each tire size. This is the aspect ratio, and in this case you're thinking of switching from an aspect ration of 55 to 65. This means you are going to be increasing the height of the tire sidewall by 10% so, multiply the width of 215 by 10% to learn that these new tires will be 21.5 mm higher than the originals.

Since 21.5 mm is almost one inch you need to see if there is enough space in your vehicle to all a tire which is more than 1 1/2 inches larger in diameter to function without bumping or rubbing in normal operation.

Some vehicles have lots of space, others are very tight ... the best thing to do is to test mount a new tire and try it out for size before making a purchase, just like you'd try on a pair of shoes.

Different size tires on the front and back.

by Joseph Godlewski
(Punxsutawney, Pa.)

Differing wheel size extreme

Differing wheel size extreme

My wife has an 05 CLK Mercedes Benz conv't. The front tires are 225/45 R 17 91W. The rear tires are 245/40 R 17 91W. Michelin Pilot primacy, brand name.

We live in Penna and need all weather tires. Can we put all four the same size all weather tires on the car ?

Do you recommend any tire being better than another for our needs ?
Would appreciae any suggestions or recommendations concerning this issue.

Would the larger tire (245/40) work on the front of the car as well as the rear ?


Editorial Comment: 
There's some interesting and valid concerns about different size tires expressed here.

One thing which causes confusion is determining the actual diameter of a tire. In this case we have the following tires:
225/45 R 17 91W and
245/40 R 17 91W

To determine the height of these tires, multiply the first number, which is the tire width in millimeters, by the number after the slash, which is a percentage. Applying this to the above numbers gives us:
101.25 mm and
98 mm

This tells me that the rear wheels are 3.25mm, or about 1/8 inch lower than the front. This is not a great difference, and could easily be erased by a difference in the wear-rate of the two wheels. (Or if one pair were older than the others.)

The only problem which might occur, if the same sized tire were used both front and rear, could be some rubbing in the front wheel well if there is very limited space and the wider tires (245) were in use. This could easily be determined by a trial fitting of the wider tire in the front, or avoid the problem completely by using the narrower tire all around.

If you're happy with Michelin I see no reason for you to change brands, but you should be aware that original equipment tires or another reliable brand won't make any difference in the performance or safety of your car. Most frequently the original equipment is decided by which tire manufacturer negotiates the best deal with the car maker -- nothing more.

Tire Concerns: Tube size

What does 6.60-13.00 mean on mower tire? I need a tube.



Editorial Comment:  Usually in mower tires, the first of the two numbers refers to the width of the tire and the second number is the size of the rim, in inches.

When ordering a tube you don't normally have to be greately concerned with the width, simply the diameter of the inside opening of the tube, so in this case you're looking for a 13 inch tube.

I've never heard of any serious tire expert making a big issue about whether or not the "P" precedes a tire's size.

Some tire manufacturers use it consistently, others less so, and perhaps there are some that never use it.

If you find a tire that you like which has all the other characteristics to meet your needs, there's no need to give any further thought to having a "P" or not.

As for variations, my preference is to stick with what the car was designed to use unless you like to experiment or are planning to use the car in conditions which are extremely different from what it was made for.

Tire Concerns: Using higher tires on rear

by arturo
(emporia,ks, usa)

Mercury Cougar

Mercury Cougar

I have 225/50R16 tires on my 1999 cougar and need to replace 2 but couldn't find that size. I've found 225/60R16 which is a little bit taller. Can I use them on the back side?


Editorial Comment:

By "back side" I'm assuming that you wish to mount these tires on the rear wheels.

As you note these tires are a bit higher than the previous ones ... 22.5 mm --which is slightly under one inch-- to be exact.

Provided there is enough space in the wheel well there should be no problem however this may have a small effect on your power output, gas mileage, and speedometer reading.

Personally I wouldn't worry about those differences, my biggest concern would be the space so that the tires do not rub or touch anything after they're mounted and in use.

Some vehicles have very little tolerance, so it's always wise to inspect them closely when changing to sizes not recommended by the manufacturer.

Tire Concerns: changing my tire size

by Trina

I have a 2006 Ford Five Hundred with original tire size of P215/60R17 and was wondering how would my car be affected if I switched the tire size to P225/55R17 or should I just stick to the original size?



Editorial Comment:

The tire you wish to use is a lower profile --55 instead of 60-- so it will be about 6mm lower than the original tire. Being a slightly wider tire you might have a slim chance of some rubbing ... check it out by trying a test fit first.

what does 6.0jx13 mean in reference to a tire?

by rohit
(kanpur, uttar pradesh, india)

what does 6.0jx13 mean in reference to a tire?
in a tire data I got this figure as rim size.



Editorial Comment:

You are absolutely right 6.0j x 13 describes the rim of a tire. 6.0 is the width of the rim while the 13 is the diameter of the tire which is supposed to be used on that rim. Both numbers are in inches. The "j" refers to the profile of the rim construction. This is the most common profile, but other profiles may exist, too.

Tire concerns: change tires and/or rims on Honda Accord

by Bob
(North Palm Beach,FL)

2008 Honda Accord

2008 Honda Accord

I bought a 2008 V6 Accord coupe that needs new tires- OEWM are far to expensive to replace with same- and I've found many affordable tires at a slightly different size. My original size tire is 235/45/18 - and I've found several great tires that are 225/45/18 -- WILL these be suitable replacements?
ALSO many locals are taking off their Acura or Honda 17" OEM setups and upgrading - could I use their 17" tire + rims on my car without hurting speedo etc?



Editorial Comment:

The alternative tires which you are considering would likely work with little to be concerned about since they are 4.5mm lower than the original tires. (235-225 x 45%=4.5).

The idea of changing the rims is not an unusual concept ... it's what is called Plus Sizing, but in reverse. I suppose you might call it Minus Sizing because what you want to do is lower the rim size by 1 inch. See our page on Plus Sizing to learn more about this. The idea is to choose tires which have higher sidewalls to make up for the loss of the diameter in the rim. Some people feel that this doesn't look as "sexy", but often the advantage is that you may be able to get tires which are lower cost if you choose one which is a popular and widely used size.

By carefully choosing the tire size, you may be able to maintain the exact same outside diameter of the tire so that there is absolutely no change in speedometer reading, power transfer and/or fuel consumption.

Good luck ... come back here and tell us what you finally did and the experience you've had.

Tire Concerns: 195/65/15 tires for 2003 Elantra

The 2003 Elantra calls for a 195/60/15, Was wondering if the 195/65/15 tire would fit?

Got a deal on these if they will fit!



Editorial Comment:

The difference in tire height between a 195/60 and 195/65 is only 5% (65-65), so the second tire is just under 10mm higher (less than 1/2 inch).

This does not seem like a substantial difference which should not make a great difference, but you never know for sure until you try them on the car. I have seen times where there was a problem because the car had experienced minor mechanical damage which was not known about, or properly repaired.

Tire Concerns: Will a 215/65 tire fit an a 1999 malibu

by Jennifer
(Manitoba)

I am currently switching to my winter tires, but all that I have on hand is a 215/65 R15 and I was just wondering if it would be all right for now, I have already put them on and they are just fine for driving but as soon as i turn right or left, they touch! Is this okay for now or is it a MAJOR problem?

Comment:

You have almost answered your own question. It is not normal for a tire to rub against some part of your car when it is operating.

If you are traveling slowly when this happens, you may not think it is important, but if it happens when you are travelling at a high speed the consequences could be disastrous.

Even if it only rubs, when you are turning and you do it at a low speed, you are causing extra wear on the tire and may even end up with that tire being worn out by doing this long before it is normal. In addition, you could be provoking some mechanical damage to your car, too, depending on exactly where the rubbing is taking place.

Please do not drive any more on these tires and switch to a more suitable size as soon as you can (like today)!

I have a corolla of 2006 make with 185/70/14 and i would like to
change all 4 to 195/65/15, with this what will be effect on the
performance on the vehicle.

Comments:

Our Tire Size Calculator will show you the effects of swapping between these two sizes. Just enter your original size and the new tire size to see the exact differences.

Normally when you do Plus Sizing you want to choose the size to provide a tire which is almost identical to the original so that differences in speedometer and fuel consumption are minimized.

Tire Concerns: tire sizes for 2001 Ford Explorer

by dave
(tillamook or)

Stock tire is 235/70 16. I have some 225/60 16 studded snow tires. OK ro run this low profile tire on the Exlorer?

Comment: Check out our Tire Size Calculator to compare these sizes.

Except for the issues highlighted by the calculator, I don't think you'd have a lot of difficulty using these tires but they are beyond the 2% range which I consider to be the best fit for tire swaps.

Since the 225/60's are both lower and narrower you won't be faces with any issues because of rubbing or size constraints, but there still are other sizes that are more suitable for best performance of your vehicle.

Tire Concerns p205/60r16 in place of p205/65r16 tires

Can i put p205/60r16 in place of a p205/65r16 tires on a car

Ed Comment:

In general terms going to a lower profile tire on a car does not present the same degree of complication that going to a higher profile or a larger tire because you have no conflict over it fitting.

We made up a Tire Size Calculator which will help you see the effects of making a change from one tire size to another.

If you feel that you can accept the differences that this change will produce, just be certain that the new size you choose is the same load and speed rating as your OEM tire, this is the biggest safety issue. As long as this is kept in mind you should face no other complications that are apart from the differences that the calculator shows you.

Tire Concerns: 195/70R14 for VW Jetta 2002

by Lauren
(Seal Beach CA)

Before I switch 4 brand new tires from a now defunct 1996 Pontiac Sunfire to a 2002 Jetta with old tires I want to know if the difference in the 195/70/R14 from 195/65R15 is ok? I know it is not the original desired size but I have 4 new tires and hate to waste the investment if I can use them on the Jetta? Student in CA.

Check out the differences using our Tire Size Calculator and you'll see that while the 14" tire has a higher sidewall, it is actually a smaller tire in overall diameter. This, in itself isn't a big problem, but you will be spending more money on gas and will be travelling slower than your speedometer shows.

The big issue, however is the rims for the tires. I do not think it is likely that the rims from the Pontiac will fit the Jetta, although trying a test fitting may prove that they do. Whatever you do, you cannot mount a 14" tire on a rim which is 15" in diameter. If, somehow, you were to get the tires on the rims they would be unsafe to use because they are not seated properly.

Can I change from P225/60R16 to P215/60R16?

I have a 2001 Oldsmobile Intrigue that has always had the wider P225. I am thinking about using the P215 as I like the narrower tire for winter driving.

Is there any safety issues in going to the narrower tire?

Comment:

Use our Tire Size Calculator to see the differences in the two tires.

The difference isn't great and isn't likely to cause any major issues, especially from a safety point of view. If the narrower (and lower) tires don't concern you, they should be safe enough as long as the speed rating and load range is similar to what you currently use.

Tire Concerns: Sizing for Snows

by Frederic
(NC)

Snow tire sizing

Snow tire sizing

We just bought a Mazda3. The base model comes with 195/65 R15 wheels/tires. The "touring" model we have has 205/50 R17 wheels/tires. I understand this to be "Plus 2" sizing, for ride and handling. Now for the tricky part ... I'm pretty sure I can put 195/65 R15 snows on a spare set of 15"rims, but can I get away with 205/65 R15 snows instead?


Editorial Comment:




The sizing you need can be calculated using our plus-sizing calculator. (See plus sizing page for a link to download it.)


210/60 R15 would be the ideal size if it is available, a 205/65 would be a slightly higher tire

Tire Concerns: Switch 205/65R16 with 225/60R16

by Jennifer
(Mississippi)

I have a 2003 Nissan Altima with 205/65R16's that I'm wanting to switch tires with a 2002 Chevy Monte Carlo that has 225/60R16's. Would this be an easy swap? The Nissan's tires are only 5 months old and I'm getting rid of it to keep the Monte Carlo and would like to keep my newer tires. Thanks for any help!

links


Editorial Comment:

At first glance this seems to be a rather workable switch since the 225/60 tires are only a small bit larger in diameter than the others.

The only possible draw back I see is with the tire width being 20 mm wider, which is almost one inch. Is there enough clearance in the wheel wells and when turning to accommodate this difference? If there is any doubt, do a test fitting to make sure. If you don't run into problems on this side it should work nicely for you.

Can I fit 215/60/16s on my Eagle Talon?

by Chad
(Canada)

I currently have 205/55/16s and wanted to know if this size difference is too much or if it could fit.




Editorial Comment:

When comparing two different tires the quick way to get an idea of fit is to simply multiply the first two numbers in the size together and compare this result to the same calculation with the other tire.

To get down to specifics, you need to divide the answers you got above by 100 ( just move the decimal point two places to the left) and you see that the second tire is 16.25 mm higher than the original.

In most vehicles adding just 16mm (just under 2/3 an inch) isn't going to cause much difficulty but because of possible variations which can be caused by body or mechanical damages, modifications and sometimes even normal wear and tear, I always will want to try a test fit before committing to a different size.

Tire concerns: width of tire

by Adrian
(Buffalo, NY, USA)

I have a 98 Camry XLE. Someone wants to sell me 18" rims with 245/Z40 tires on them. Can I put them on my vehicle and not have any problems?



Editorial Comment:

The question you've asked is really impossible to answer well because it's like asking if you'd look OK wearing a pink shirt without my knowing anything else about you other than that you're wearing Nike running shoes.

The important issue for you to determine if the diameter of the new tires on the new rims will be the same (or almost the same) as the tires you are now using, and whether or not the width of the tires is suitable for the space that your vehicle has to allow for turning without rubbing. This is, of course, assuming that your present tires are not causing any problems.

Our article on Plus Sizing may help you assess this issue.

Tire Concerns: CHANGE REAR TYRES FROM 185/70/R14 TO 195/65/R14

by SITESH GOSWAMY
(NAVIMUMBAI,MAHARASTRA,INDIA)

IN MY SWIFT DIESEL CAR ALL FOUR TIRES ARE 185/70/R14 I WANT TO CHANGE REAR TIRES TO 195/65/R14 FROM 185/70/R14

FOLLOWING ARE MY QUESTIONS.

1.WILL THE LARGER WIDTH REAR TYRE EFFECT SPEED

2.WILL LARGER REAR TIRES INCREASE/DECREASE DIESEL CONSUMPTION PER KILOMETER RUN


3.WILL LARGER REAR TIRES PUT UP INFERIOR/SUPERIOR OVERALL DRIVE QUALITY FROM PRESENT ALL FOUR EQUAL SIZE TIRES.

4.WITH LARGER WIDTH REAR TIRES THAN FRONT WILL VEHICLE STABILITY BE INFERIOR/SUPERIOR THAN PRESENT ALL FOUR EQUAL SIZE TIRES.

5.WILL THE SUSPENSION BE EFFECTED ADVERSELY BY LARGER SIZE REAR TIRES.

6.WILL SIZE 195/65/R14 TYRE RUB WITH REAR WHEEL WELL OF SWIFT DIESEL CAR

7.WHAT ARE NAMES OF MANUFACTURERS WHO MAKE 195/65/R14 TIRES.

Comments:

Several of your questions can be answered by using our Tire Size Calculator. Follow the link to try it!

In reality the 195/65 tires are smaller in diameter than the original tires but the difference is small. Performance may be affected in a small way, but not so much that you would notice it.

The extra width of 5mm on each side of the tire probably will not cause any problem in the wheel well, but a test fitting is always a good idea before making a purchase. I doubt if you would notice any difference in the comfort of the vehicle or have any suspension problems.

Most major tire companies would likely have this brand, but you need to discover if they are easy to obtain where you live.

The biggest concern when using two different sizes, for many, is what you are going to do for a spare tire. It is not a good idea to mix different tire sizes on the same axle, so you usually want to have 2 spares. But with a difference in size of only 5mm, this is not really a big issue.

Tire Concerns: 215/70R15 vs 235/70R15 how size change affects truck

by Chris
(Temecula CA)

2009 Toyota Tacoma Access Cab

2009 Toyota Tacoma Access Cab

I have an '09 Toyota Tacoma Access Cab--the smaller 4 cylinder model.

The one thing that I have always disliked about the looks of the truck is how small the tires look compared to the wheel wells.

It is now time to start thinking about new tires. I currently have 215 70 15 on the truck and was thinking of possibly getting some slightly larger tires.


I saw a similar truck that was running 235 70 15's and they filled the wheel wells better.

If I go with this larger tire how will it affect the handling of the truck. I drive about 45K a year on California highways.

My goals would be:
1. to fill the wheel wells
2. any better smoother ride
3. quieter ride
4. know any tires brand/models you can recommend.



Editorial Comment:

Let's examine your objectives one by one.

First, these tires will certainly be larger than those you already use. They will be 20mm wider and about 16mm higher. This does not look like it would cause any problems space-wise in your wheel well, but it is always best to try a test fitting first before committing to buying.

Your ride may be a bit softer because you will be using a lower tire pressure. You may or may not like the handling characteristics of a lower pressured tire, but there will be some difference, so don't be surprised.

Also, don't try to run the same pressure as your original tires, or you'll find that the center of the tread will wear down faster than the shoulders. Exactly what the difference in pressure will be is something you'll have to learn by experimenting and watching how your tires are wearing.

I suggest you start with about 2 psi lower. Monitor your tread wear for the first few months and lower it a bit more if the edges aren't being worn as quickly as the center of the tread. Increase the pressure if the wear is the other way round.

Once you find the best pressure, write it down and stick it under a plastic cover on your driver's door post, so you won't forget.

The quietness of the ride will depend to a great extent on the tread design you choose. If you pick a more aggressive tread that you had before, expect more noise. If you choose a similar design, there shouldn't be a great difference.

As for specific brands/designs I won't recommend any because it would be best to talk over your specific needs with a local dealer who would be in the best position to recommend what is most appropriate.

With larger tires on this vehicle you should expect a slight reduction in power, a slightly lower fuel consumption and a lower reading on your speedometer than you are actually traveling.

Tire Concerns: 17/8 rims on a 2002 Honda Civic

by Brian
(Calgary, alberta)

Can a 17/8 rim fit a honda civic 02 without altering my springs, and what size of tires can i use?
I imported advan racing wheels from the philippines and the size is 17/8", i don't have any tires yet cause im still researching on whether this rim size would fit my car a honda civic 02,my friend says it fits my civic but when i ask a tire shop about what size should i get for my rims they say that i better ask a honda dealership about it cause they dont have it on their chart? It made me think that i got the wrong set of rims

Comment.

Use our Tire Size Calculator to find a tire size for 17" rims that is within 2% of your original OEM tires and you'll not have to make any body changes. Enter the OEM tire size in the Current tire area and select 17 for the new tire's rim diameter.

That will take care of the tire size. Whether or not the rims will work depend on the bolt pattern your car uses and those on the rims. If they match, you're home free but if they don't then you need to find the ones which are made to fit on the car.

Tire Concern; Changing to smaller tire size

by Kevin
(Edmonton Alberta Canada)

I have a 2003 Chev Silverado
the tire on it now are 235-75 R 16
and I have a chance at free winter tires but the size is different

tires now are 235-75-R 16
like to replace with Goodyear Nordics
215-65-R 16 will this be ok?

Note: I do not carry any weight in the truck box at all.



Editorial Comment:

What is being considered here is the possibility of installing a smaller tire going from 235-75 R16 to 215-65-R16. Note, from the first number in each size that the second tire is narrower by 20mm (235-215) and also a lower aspect ratio (65 vs 75). These two factors combined result in the second tire being 36.5mm lower, which is roughly 1 1/2 inches.

As long as you don't need the clearance beneath the vehicle this change should not produce any significant problems.

Because the diameter of the new tire will be less than the original you can expect that you'll have more power delivered to the wheels, but your speedometer will under read because you are not advancing as much for each rotation of the wheel, and this too may affect your fuel consumption.

Comment

Check our Tire Size Calculator to see the difference, but the 215/60R16 is a smaller tire than the /70 tire.

It will certainly fit on the wheel and likely have no problem fitting on the car either, but it is the effects of using a smaller tire that you need to consider to see if they are worthwhile. The Calculator will tell you what those differences are.

Tire Concerns: 2006 malibu lt 215 60 16 to 225 60 16

I have 4 2000 impala steel wheels with 225 60 16 tires on them, will they fit on a 2006 malibu lt?

Comment:

Why don't you just try putting one of these on your car in the space that seems to have the least amount of room and see if there's any problem?

The 225/60 tire is just 10 mm wider (less than 1/2 inch and the extra height is just 60% of that difference, so there's not a lot of difference in either height or width between the two tires.

You'll soon see if there is any problem with the wheel bolts matching or not when you try on one .. if you have to force the wheel on to get in mounted, forget it because they won't fit, but I'd guess there's a good chance this won't be an issue.

Tire Concerns re changing P215/50/r17 fpr 205/50R17

by Jimmy
(Alaska)

I'm looking for snow tires. Does it make a difference if I put P215/50/r17 on a mazda3 with 205/50/r17?



Editorial Comment:

The tires you are considering are 10mm wider and 5mm higher (50% of 10). This difference does not seem like much, and may not be noticeable except in some vehicles where the existing tire is already a tight fit and there isn't enough space in the wheel wells.

Do a test fitting in the most restricted spot, check out the movement when you turn your steering wheel to the extremes and if you notice no problems, you're likely quite alright.

Change tires with different aspect ratio/size.

by anthony
(tucson,AZ)

Can I change front tires with WWW/65RDD to WWW/70RDD size? (Back tires still same size). Where: WWW=width, and DD=diameter

If the change of size applies to all four tires would it be more acceptable?



Editorial Comment:

Maybe this would be a bit more easy to understand if Aspect Ratio were called "Height". The number (65 or 70) in your example is, of course, not the height but it is a number which is used to calculate the height from the width. The AR is a percentage and the larger the number, the taller your tire will be. Exactly how much taller, will depend on the width you start with.

So, in your hypothetical example, increasing from a AR of 65 to an AR of 70 means you will be increasing the tire's height by 5%.

If you put the taller tires on the back you'll be raising the rear of the car up a tiny bit ... typically around 1/2 and inch for most passenger car tire sizes. Doing it all around of course raises the entire car.

The only other issue you might consider is the space in your wheel well. Very often a small change, like 5% of the tire's width won't make a significant difference, but sometimes you will end up with rubbing or other difficulties.

It's always a good idea to do a test fitting on the wheel where there seems to be the least room before switching all four wheels.

Tire Concerns: replace S60 215/55R16 tires with 205/65R16

by Alberto Barquin
(Queretaro, Mexico)

I have a Volvo S60 2004 and the tires specification is 215/55R16, my brother has a set of 4 new tires with a different specification (205/65R16) and I want to now if I can use them.



Editorial Comment:

A very quick and approximate way to tell is two tires are equivalent is to multiply the first two numbers in each size together and compare the results. Here you have 215 x 55 = 11825 and
205 x 65 = 13325.

Immediately we can see the second tire is higher because the product is bigger. Convert these numbers to measurements and we see that there is a difference of 15mm, or just a bit over 1/2 in the tire height.

The question is whether or not your Volvo has enough space in the wheel well to accept this much difference (which is really not very much). Do a test fit with one wheel in the one which has the least amount of space and you'll see.

Tire Concerns: Will 225/55R16s fit my 2011 Hyundai Elantra

My car 2011 Hyundai Elantra `presently has 205/55R16s on it. Will 225/55R16 fit?



Editorial Comment:
Here are the calculations relevant to your case:
Original tire
Sidewall: 4.44 in
Radius: 12.44 in
Diameter: 24.88 in
Circumf: 78.16 in
Revs/mile: 810.68

New Tire
Sidewall: 4.87 in
Radius: 12.87 in
Diameter: 25.74 in
Circumf: 80.88 in
Revs/mile: 783.41


Speedometer reading with new tire is 3.48% too slow.
When your speedometer is reading 60mph you are actually traveling 62.02mph

You may experience some problems with space in the wheel well due to a larger diameter, and you'd be wise to do a test fitting before committing to these tires.

A better fit for you vehicle would be 225/50R16 where there is only a sliver of difference in height and diameter.

Tire size

by Leo
(Bronx, NY)

I have a Toyota Camry SE 2010, The
tire size for that vehicle is P215/55R17
but I changed it for tire size P225/50R17.
Is there any change in the car performance
for using that tire or is the same?

Comment:
See our Tire Size Calculator to find out the exact differences between these two tires. There definitely is some difference, but they are less than 2% which is the limit I think one should try to stay within.

Tire Concerns P215/65R17 for 2006 Equinox.

Can u put P215/65R17 Interstate Goodyear Tires on a 2006 Equinox.
Tires are on the front, Consumer Guide states specs Front Wheel material- P235/65R16. I am worried about the space between the top/side of tire and spring/shock.

Editorial Note:

We have created a Tire Size Calculator to help with questions like this.

Check out the calculator and you'll see that the 215/65 tire is smaller than the 235/65 tire so you're not likely to have any issues with a lack of space. There are other issues which the calculator will point out, but if you are thinking of only changing 2 of the 4 tires this is not usually a recommended practice, even on a vehicle that is not 4x4 … and certainly to be avoided on a 4X4 because of potential mechanical damage which this can provoke.

If you absolutely must change only 2 tires, make certain that you keep both tires on each axle the same size. This gets complicated if you have a flat tire sometime and are not carrying a spare tire of each size.

Tire Concerns: Plus 0 sizing on one axle only

by Andy
(Chicago Heights, IL)

I have a car with 205/65r16 tires, which I couldn't find at any retailers. The salesman sold me TWO 215/60r16 tires which he said I could rotate just fine. Is this true or not?



Editorial Comment:

This really isn't what Plus Sizing is about. In any kind of plus sizing the objective is to end up with a different width of tire that has the same diameter as before.

In your case you have had a tire installed that is just slightly smaller than the original -- 8/10th of an inch, so you are losing 4/10th of an inch in ground clearance. Your speedometer will read differently by about 3% and your fuel consumption will increase if you are putting them on the axle which drives the car.

Now, if you keep them both on the same axle, there should be no other problems unless your vehicle is 4WD. A mis-match of sizes on a 4WD car can result in serious mechanical damage but if it's not 4WD, then you should be OK.

Tire Concerns: 215 45 R17 for 94 accord

by Joel
(Boston, MA)

I have 17inch rims for my 94 accord EX. I was told that for 17" rims I will need a tire size 205-45-17. My question is will a tire being 215-45-17 fit it without problems? Am looking for the chippest tire/rims to fit on my car and this is the only size I can find within my budget. I would appreciate any help.

Ed. Comments:

You are asking if it is OK to increase the tire width by 10mm (less than 1/2 inch) on the same rims.

Under most circumstances this would not likely cause any problems. The standards for most tires allow them to be used on a range of rim widths which are usually 1/2 inch smaller or larger than the recommended width in the rim. Since the tire width in your case is not changing by that much, there doesn't teem to be a problem.

Take note, however that the aspect ratio is staying the same, but because the tire height is calculated by using this AR there will be a change in the tire's height … here it will be 45% of the difference in width or 4.5 mm. That is less than 1/4 inch and is very unlikely to cause any problems.

Even so, use our Tire Size Calculatorto compare these two tires and see the effects of changing. I don't think you will find it excessive, but that's up to you to decide in the end.

Tire Concerns can a 99 corolla ve USE p175/75 r14

by Doug Richardson
(Bremerton, WA)

have a chance to place the p175/75 r14 studded tires on 1999 corolla ve?

Comment:

You've not provided us with the original tire size from your vehicle so it may be impossible to give you a precise answer.

According to my knowledge the 1999 Toyota Corolla came with two possible OEM tires 175/65R14 and 185/65R14, but it could be that yours is a different model and had a different size.


When you know that size, plug it in to the Tire Size Calculator and compare it to the 175/75R14 which you're wondering about and you'll see that it is a slightly larger tire (compared to the two sizes I've mentioned) and the effects of that increased tire size. If you have enough room and are prepared to accept the consequences, you can likely use this tire on your Corolla, but I'm waffling a bit now because I don't know what size to compare this tire with.

Tire Concerns: Will a 195 tyres fit a 7J rim?

by Keith
(Hampton, Middlesex. UK)

I have puchased a set of 15x7J rims with 205/60x15 tyres fitted to them. Unfortunately they are worn out but I do have a full set of newish 195/55x15 tyres already on my vehicle. Will these safely fit onto the 7J rim?



Editorial Comment:

According the the specifications I have available the 7" rims are the maximum that would be permitted for 195/55R15 tires.

It is good to check the rim width permitted for each tire size before making a switch, especially if you are using rims which are different from those originally installed in a vehicle. If you do, you can never follow the recommendations of the maker but have to be guided by the design characteristics of each tire in question.

will 225 60 r17 be ok on a 2002 sts cadillac?

by Doug
(Rapid City SD)

will 225 60 r17 be ok on a 2002 sts cadillac?

Comment:

I believe the OEM size for this vehicle was 235/55-17. I would use this size or your current tire size in our Tire Size Calculator to compare the differences. As long as you have the right wheels and stay within 2% of the original size you can generally make the switch without difficulty.

Tire Concerns; Sizing Up

by Ellie
(North Carolina)

I currently have a ScionXD that needs new tires, however not many places sell or carry the odd-ball 195/60R16 stock tires that the Scion comes with. Would a 215/55R16 be ok to use instead WITHOUT affecting anything major in performance or mileage? If not, what one size bigger CAN I use with the same stock rim in order to make my search for tires easier?

Comment:

Check our Tire Size Calculator to compare the two tires but I find your choice to be within the 2% range of size difference that is acceptable to me. You might also consider the 205/55R16 which is not quite as wide and could be less of a problem if the extra width causes problems with space in your wheel wells.

Tire Concerns: Larger Sizes

by michael faloon
(fair lawn nj)

i have a 2003 kia rio with 175/65r14 tires Will a 205/75r14 fit?

Comment:

See our Tire Size Calculator to learn the differences in these two tires.

The 205/75 is considerably larger and perhaps it may not even fit on the rim you have because it is also wider and may require a wider rim than the one which your original tire is using.

You are definitely getting into customizing your car if you switch to this tire, you may have to make some mechanical changes to have it fit, and unless you want to get into these things I would not recommend this swap.

Tire concerns: larger tires / rims on 2006 Kia Rio

Can i use 16 inch rims plus tyres 205/45HR/16 on kia rio 2006 whee the spec range is 195/50/15?


Comment:

Use out Tire Size Calculator
Tire Size Calculator to compare the tire sizes and if the new size is within 2% (the default setting on the Calculator). you should be OK for tires.

You also need to make sure you have wheels which fit your car, by matching the bolt pattern and the wheel offset. When these two conditions are met, you should be OK to use larger, lower profile tires.

mixing tire sizes

by Leslie Weeks
(Tulsa, Oklahoma, USA)

I have 3 p265 tires and one lt265 tire on my Tahoe. Three need to be aired to 35psi and the lt tire to 80psi. I had a flat and got a temporary one to replace the flat. Will this be bad for a few months?

Comment:

Something is definitely very wrong with your tire set up as you describe it. It seems to me that you may have been inflating the LT tire to the MAXIMUM pressure which is marked on the tire sidewall. The Maximum pressure is not the pressure which is normally used, and that tire, I would be almost certain, should carry the same pressure as the other tires.

You can usually find the recommended tire pressure on the Driver's side door pillar, or in the vehicle user's manual. Use these pressures and NEVER the maximum pressure on the tire except for very special and unusual situations.

You did not specify what the size was for the temporary tire which you acquired, but for best results it should be the same size, load and speed rating as your other tires. Otherwise, use it only to get to the nearest repair facility.

Tire Concerns: can i replace my original 14 inches rims to 16 inches rims for my 1998 hyundai elantra station wagon?

by soyti
(Scotland)

I have a 1998 Hyundai Elantra Station Wagon which has an original rims of 14 inches, front and rear. Then I bought a new rims and tires with a measurement of 215 60 R16. I would like to change my original rims and tire to R16.

Comment:

You are considering what is called: Plus Sizing and I'd recommend you read up on it to learn the basics.

Normally, there isn't much of an issue when you want to switch to larger rims so long as you adjust the tire size (the profile) to compensate. When a person wants to switch to smaller rims there is a possibility that there may not be sufficient clearance inside the rim to allow the brakes or other parts to function correctly.

Usually you want to end up with tires which have the same or very close to the same diameter as what your car originally came with and sometimes you may even see new cars being offered with optional rims which are larger. This, of course, is an indication that this kind of switch has already been tried and is suitable from the cars designers.

Tire Concerns: tire size

My 2010 Camry LE has 215/60/R16 standard tires. Can I use 235/60/R16 winter tires, or are they too wide.

Comment:

Whenever you want to compare two tires, it would be good to use our Tire Size Calculator o see the effects.

This will show you not only the size differences but the way those differences will affect the performance of your car, such as gas mileage and speedometer reading.

The 235 tire is not only wider by 20mm (which is almost an inch) but it will be taller by 60 percent of that difference because the aspect ratio of the two tires is 60.

So you will have a tire which is both wider and higher and this, of course may provoke a problem with space meaning that the tire could rub either constantly or only when turning or running over bumps. The best thing to do is to do a test fitting in the area that seems to have the least amount of space … usually the front wheel well, and if you are testing in that area then try turning the steering wheel from one extreme to the other and observing under the car if there is any obstruction.

If there is no obstruction, then you lower the car to the ground, and notice that there will be some settling which, again, will change the amount of clearance which is available because of the effect of the weight of the vehicle. If it looks close then you have to make a careful inspection before trying a road test.

On the other hand, if there is lots of room, then you may not have to do any further testing.

It is wise to try a test fit even if you know someone else who has used the same tire without problems. It is possible that your vehicle might have some mechanical difference that the other vehicle didn't have and this could be enough to make it impossible to use the tire.

I remember one client who had used a larger winter tire the previous year, and when he returned to swap the summer tires with the winter tires a second season discovered that the same tires were rubbing when he turned. When we looked further into the matter we discovered that he had had some mechanical work done on his steering or suspension (I can't remember which) but the effect was enough to make the larger tires rub in an area where they hadn't rubbed before.

Good Luck

Tire Concerns: Alternate sizes to 215/50 R17

by Edward
(Kitchener Ontario)

have tire sizes 215/50/17 low profile what other type can I install in my car
Got a Mazda Milenia but the tires are the low profile kind. I wonder what other tires sizes can be installed in my car instead, so I can have more choices. Size tires are 215/50/17 low profile for exemple If i want to go from low profile to a regular profile.

Ed Comment:

There are several sizes that would conceivably serve as alternatives to 215/50 R 17 tires and this is what our Tire Size Calculator was initial designed to show. Just enter your original tire into the top part of the calculator and 17 into the lower part while leaving the percentage difference at 2%.

The sises you see will provide approximately the same service as the original with little changes in performance or fuel consumption. You still need to be careful that any wider tire you might like to use will fit in the wheel well without any rubbing, especially when turning, but apart from that and making sure you choose a tire with the same speed and load rating (or greater) you're home free.

Remember, too, that you can click on any tire size that is calculated to get a more detailed comparison with your original tire.

Tire concerns:do 215/65R16 have same diameter as 225/65R17

by Neal
(Alberta)

I have a set of 215/65R16 winter tires and rims and I just bought a 2011 Equinox with 225/65R17 and was hoping the winter ones would fit.



Editorial Comment:

If your 215/65R16 tires are already mounted on rims, the only major concern about fitting is if the holes in the rims match up with the studs on the vehicle. If they match the rims and tires might work.

There will be a noticeable lowering in height because of the smaller rim diameter and the narrower tire with the same aspect ratio. If you can get by with a lesser degree of ground clearance, and realize that your speedometer will not read correctly, you can use these tires.

Tire Concerns: P245/70R16 106s vs 245/70R16 107s. tires

I have 3 P245/70R16 106s tires and replaced 1 with a 245/70R16 107s. Is there any cause for concern with the trade off. Had a nail in side wall and had to replace. Does the P in front of the numbers going to effect my vehicle.



Editorial Comment:

I'm not very good at mind reading, so I don't know if there is any cause for concern or not.

The P in front of the numbers is used by SOME tire companies to specify that the tires are made for use on Passenger Cars, but other companies don't do it. Since we don't know if your vehicle is a car or a light truck or a SUV, it is hard to say. Apart from that, the replacement tire is just rated for just a slightly higher load than the one it replaced and the speed rating is the same, so, in theory, there should be no cause for concern.

Whenever you ask questions it's good to give as much information as you can ... too much is better than too little. Tell us what kind of vehicle you are using, what driving conditions and kind of roads and anything else which might affect how and why you are using your tires. If you don't the answers you receive might not be the best for your situation.

Tire Concerns: Smaller Tire width

by Herbert Wilson
(Westminster, MD)

I currently have 265/75/15 on my light truck. Can I safely drop down to a 235/75/15? The width difference appears to be a little over 1 inch smaller.

Comment:

See our Tire Size Calculator to calculate the difference in the two sizes.

The radius of the tire is about 9/10th of an inch less which is usually much more significant than the tire's width when you are looking at a smaller tire.

Notice, in the calculator the speedometer differences and fuel consumption that this change will produce, if you are prepared to accept these differences, the size change would be workable even though it is outside the normal range which I like to recommend.

I do not see any safety issues in this change.

Tire Concerns: P205/70R15 tires for 2001 Oldsmobile Alero GL

by Mark
(Belgrade, MT)

Will a P205/70R15 tire fit on my 2001 Oldsmobile Alero GL? A friend has a set of Cooper P205/70R15 tires that are new that I can get very cheap. My car should have 215/60R15 tires on it. Will these tires work?

Comment:

To be entirely practical we seldom recommend that people switch to a different sized tire that is more than 2% different in diameter and the size your friend has is almost 5% larger. You may or may not have problems with clearance and will experience a drop in fuel efficiency along with an error in the speedometer reading.

With the way fuel prices have been going you may want to find another friend who has tires a bit closer to your own!

14" wheels on a 95 accord ex wagon?

by Charlie
(Cherry Hill, NJ)

Stock size is 195/60/15, I want to use 14" for snow tires. Will the wheels clear the brakes and work? I would use accord LX 14" wheels.

Comment:

Since other models of the Honda Accord from 1995 came with 14" wheels as OEM, there is a good chance that you could use the wheels and that they will fit without interfering with the brakes, however, the only way to know for sure is to try a test fitting with the wheels you now have and see if there is any problem that you can notice.

Use our Tire Size Calculator to choose a size of the snow tire that is within 2% of your original tire if you want to have the best results.

Tire Concerns: Installing 215/65R16 tires on a car that uses 215/55R16 tires

by Rick
(Lansing, NY)

Will 215 65 16 snow tires work on a car that uses 215 55 16 tires?



Editorial Comment:

This issues involved in increasing the aspect ratio (from 55 to 65) is that you are ending up with a higher tire ... in this case 10% (65-55) of the width, or 21.5 mm. This is nearly one inch.

The very first thing you need to determine is if you have enough space to allow that extra size to work and move freely without rubbing or bumping on any part of the car. This, is the most important consideration for a change of this magnitude.

Next you will end up with the car travelling slightly faster than what the speedometer shows, you will have less power transmitted to the wheels, and your gas mileage may improve by a small amount, compared with a tire of the orginal size.

For more information read about Plus Sizing which compares ways of changing wheel sizes to maintain outside diameter.

Tire Concerns: 215/60R16 snow tires vs 225/70R16

by Mike
(Syracuse)

I have two 215/60R16 snow tires from a station wagon I sold. Can I use these snows on the van I bought whose four original tires are 225/70R16?

If I can use these snows, can I use the two 215/60R16 snows on the front wheels and two of the 225/70R16s on the rear wheels? Or would I have to use four tires of the same size?

Comments:

If you will check our Tire Size Calculator to see the differences you'll see the snow tires are smaller than the other ones.

Regardless of tire size, you would always want to mount your snow tires on the drive axle of your vehicle for the traction they will provide, if you only have two.

As long as you do not have a 4WD drive vehicle, there is no safety or mechanical problem in mixing sizes but you do want to keep the same sizes on the same axle to avoid any stability or handling issues.

You likely will not have any problems with the smaller tires fitting but possibly, depending on your vehicle and driving conditions there could be some concern over clearance because of the lower tire.

Tire Concerns: will 225/60r17 work in place of 225/65r17?

by Greg
(Rockford,mi )

the 225/60r17 are snow tires. The 225/65r17 are stock tires.
The car is a front wheel drive 2005 Lexus RX330.

Comment

See our Tire Size Calculator to compare your tires and get the exact differences.

Usually if doesn't make a lot of difference if you are putting on tires which are slightly smaller than your original tires unless you have very limited ground clearance and you are concerned with bottoming-out in the areas where you drive. Obviously if you have an issue with scraping with your current tires, anything that gives you less clearance will only make the problem worse.

In your case you are losing only about 11mm of clearance which is not likely to be too much under normal driving but you are the best judge of whether this is a concern for you.

Tire Sizes for my 2008 Town & Country

by Warren
(Burlington, Ontario, Canada)

I'm looking for winter tires and the all season size on my van right now are 225/65R16's.
I have an opportunity to buy winter tires that are 215/65/R16's with rims. Is it ok to use the 215's instead of the 225's?
Also, two of the proposed winter tires say WS50 and the other two say WS60. Does this make a difference if I mix them?

Comment:

Check out these two tires using the Tire Size Calculator and you'll see the 215 tires are just slightly lower that the 225's. Unless ground clearance is a big concern for you this shouldn't be a problem.

It seems to me that you must be referring to Blizzak tires, since the WS50 and WS60 seem to be model numbers which Bridgestone uses. I'm not entirely familiar with the difference between these two so I can't guide you completely, but as long as you keep one pair on the same axle I don't think there would be any major issues in using two different types at the same time. I would put the ones with the most aggressive tread design on the drive wheels.

Tire Sizing

by M.Maldonado
(Oklahoma)

This may be a silly question, but i figure i'd ask anyways. I have a 99 mercury cougar and need to replace one of the tires.

The size on there now is 225/50/R16, a bit oversized i know, but they came with the car when i bought it. What i'd like to know is, can i use a 205/60/R16 tire on it instead of the factory 205/60/R15, because i have 16inch rims & not 15.

I also have the option of using 215/50/R16 but have found them to be a bit expensive. So, would it hurt to use a tire with an aspect ratio of 60 instead of the 50? what is the difference between the two? and would there be any differences in performance/handling?

Comment

See our Tire Size Calculator to find out the difference in the sizes. You can compare both your existing size and the original OEM size with any other size you wish in any rim size.

Generally when you increase the rim size you will decrease the Aspect Ratio so that the new diameter is about the same as what you started with. Normally, in Plus Sizing people try to stick with the same tire width (the first number in the size).

Whenever you increase the AR, you are making the tire higher and this sometimes results in not having enough space in the wheel well, along with other issues which the calculator will illustrate for you.

Normally I recommend that you stay within 2% of your original tire size to get the best results.

Tire Concerns: using 205/55R16 snow tire in place of 215/60R16 tire

What are the effects of using a 205/55R16 snow tires on a car which has 215/60R16 regular tires?



Editorial Comment:

The thing to note here is that because the aspect ratio is going from 60 to 55 on a tire of the narrower width, means that the "new" tire will be slightly lower than the original by 5%.

In most cases switching to a slightly lower tire will not be as likely to cause problems as much as a higher tire might, because you will not run the risk of bumping or rubbing because there isn't enough room.

The only issue that might come up is that of having less ground clearance, but even here, because there isn't that much of a difference in height, the loss is not likely to be noticeable unless, you have already found that you sometimes scrape the ground with the tires you normally use.

Gas mileage will be reduced slightly and your speedometer will show that you are going slightly faster than it would normally show by about 2-3%.

Tire Concerns: change 235/55 16 to 235/60 16

by Jeff
(Murfreesboro Tn.)

I have a 1997 s-10 2 wheel drive extended cab. I need new tires and it has a 235 55 r16 on it now. These are on factory rims and the tire size is hard to find. I was told at one tire place to change to a 60 instead of a 55. Can this be done without any problem, or will the tire rub?

Ed Comment:

Compare these two tires using Tire Size Calculator and you'll see that there is a very small difference between them and you're not likely to run into any difficulties in making the change.

The calculator may reveal other tire sizes that will be equally easy to obtain that would also be within an acceptable range that you can consider, too, but if you're getting a good deal on these ones you might as well go with them.

Tire concerns: Difference in tire size between a 40 and a 35??

I have a 02 Camaro SS and I am looking for tires. The problem I am having is the tires that came on the car are 285/40/zr17. I have a 17x9.5 rim. It is very hard to find a tire that fits that size, that is any good. Now my question, if I buy front tires at a size of 275/40/zr17 and the rear tires 315/35/zr17 would the sidewalls look funny and will the car set lower in the rear?



Editorial Comment:

If you calculate the tire sidewall height of each of these two tire sizes, you'll find that they are almost exactly the same. (315 x 0.35 and 285 x 0.4 both come out to apx 110 mm.)

So, the back will not be anywhere lower than the front and you'd not likely be able to notice any visual difference when looking at them.

The only possible problem might come from the mounting of the wider tire on your rims. I don't have the specs available for each of these tires, but supposing that the narrower tire is using the ideal rim, then it seems that the wider tire should be acceptable for that rim. The best bet is to ask your dealer to tell you what is the recommended and acceptable rim width for each of these tires.

My 1999 VW Jetta recommends 195/65/15. Will 195/60/15 work?

Comment:

Plug in both of these tire sizes into our Tire Size Calculator and you'll see that the 195/60 is a bit smaller thant the 195/65 tire. The calculator will highlight the differences between the two.

Generally speaking there is not as much difficulty in considering a smaller tire using the same wheel on any car because there's no problem with space. You do lose some ground clearance but if you are driving in circumstances and roads where that is not an issue, then you don't have to worry about that.

In most cases a difference of no more than 2% will not bother most people and these are the best swaps to make when you do it. In any event, it is best to change all 5 tires (remember the spare) and avoid mixing two different sized tires on the same axle.

different tire size on the rear than factory

by vic
(canada)

My husband has installed my winter tires and the rear tires only are different from factory specs. My truck is supposed to have 205/75-15 size tires but the rear tires he installed are 235/75-15. My question is how will this affect my spedo reading? If I am traveling at 50km/h according to the spedo am I actually going faster than 50km/h because of the larger size tires on the back? If so am I going faster or slower and by how much? I'm not interested in getting a speeding ticket.
Thank you in advance!


Editorial Comment

You will definitely be travelling faster than your speedometer reads by a factor of nearly 7%. The exact difference is 6.54%.

Normally I do not like to see any tire swap which is great than 2% from the original unless the owner of the vehicle is prepared to experience some radical differences. I especially do not like to see mixed sizes on a vehicle except where the vehicle was designed for that case. You never, under any circumstances want to mix different sizes on the same axle.

You say you have both the larger tires on the rear which may be fine at the moment, but what happens if you have a flat tire and need to change to the spare? Are you carrying an extra spare?

Replacing 215/65R16 for 225/65R16 on a Chrysler Town & country

by Cynthia

I have a 1999 Chrysler Town & Country van. They currently have 215/65R16 tires but are like bald. A friend has a set of tires from his old Entourage van that are like new. They are 225/65R16. Can I put these on my Town & country? Would it cause any issues? From what I've read it seems like such a small change. Someone please let me know. If they will work I need to change them ASAP, before it snows again:) thanks.

Editorial Comment:

Indeed the difference between a 215/65R16 tire and a 225/65R16 tire seems small. The latter is 10 mm wider (225-215) and 6.5mm higher (65% of the 10 mm extra width).

Using our Tire Size Calculator you can compare these two tires to determine the exact differences.

The calculator shows that these two tires are less than 2% different in over all size and thus are a swap that I could recommend even though you will have a slight speedometer error this shoudn't cause any major difficulty unless you are constantly in the habit of pushing the speed limit to it's maximum when driving. You will also have the benefit of a small improvement in fuel use.

The only thing you want to check is to make certain that the speed and load ratings of the new tire is equal or greater than what you originally had, otherwise this could end up with you using a tire which is not designed for the weight and speed your vehicle has.

2008 Chevrolet Trailblazer

2008 Chevrolet Trailblazer

I have an 08 trailblazer and I have 245's on them my neighbor gave me 2 265's can I run with the 245's on the front and the 265's on the back?

Editorial Comment:

We have to fill in lots of missing information so you may not be getting the right story in what follows. To save yourself time and make sure you get the right information always give as much and as complete information as you can, even including a photo wherever possible when you write in to ANY website unless you are writing to a psychic's website.

To start it seems you are referring to the 2008 model year of the Chevrolet Trailblazer which was made by GM. If this is correct it refers to the first generation of the Trailblazer which ran from 2002 to 2009. These came with 4 wheel drive as an option unless it was an SS model which had all wheel drive.

Usually the owner's manual of any 4 wheel drive or all wheel drive vehicles make a point of stating that all 4 wheels need to have the same sized tire installed or else serious damage can be caused to the transmission or differential components due to the difference in the operating circumference of the different sized tires.

So, based on this view you are running a high risk of having serious mechanical damage if you install different sized tires on you Chevy Trailblazer.

Can I put 215/55/17 tires on a 2007 Honda Accord

by Ron
(Wheaton, Illinois)

I would like to put 215/55/17 tires on my Honda 2007 Accord. Factory tires are 215/50/17.

The tires are brand new and are currently on a lexus.
Also, can I just exchange the Lexus wheels with the Honda wheels, they seem to fit just fine in a test.

Why, Lexus had the brand new tires and was in an accident with no damage to the new tires or wheel.

Editorial Comment:

The Lexus tires which are 215/55 R17 are just slightly larger in over all diameter than the 215/50 R17 from your Honda. The actual difference is 5% of 215mm, times 2, making them about 21.5 mm bigger. This is about an inch (exactly 0.85 inches) which is roughly about 3% larger.

Because I don't like to see a difference of more than 2% in sizes I don't recommend this swap. Since you didn't specify the year and model of the Lexus, I couldn't verify the wheel fittings, but if you search a web site that sells wheels and compare the bolt patterns for the two vehicles you should be able to determine if the wheels would fit.

225/70r16 on a 2000 olds alero

by Jordan
(Essex Vermont usa)

I have a 2000 Oldsmobile alero will tires sized 225/70r16 fit on this car?

Editorial Comment:

The 2000 Oldsmobile Alero came in a variety of different models so it is possible that my comment may not apply to yours. For the 2000 Oldsmobile Alero GL Sedan, OEM tires of 225/50R16 were an optional size offered and this is MUCH smaller than the 225/70R16 that you are contemplating.

There is more than 14% difference is total diameter of the mounted tire and we seldom recommend that a tire swap greater than 2% difference is suitable unless you are prepared to accept considerable variations in performance. In addition, with such a great difference in size you may even find that this will not fit within the space available or will result in some rubbing or restriction in movement. The only way to know for sure is by making a test fit before making a commitment, but I wouldn't even try, in this case.

Tire size change for 2013 Dodge Grand caravan

by Troy
(Nova Scotia)

my 2013 Dodge Grand Caravan currently has a set of 225/ 65/ R16 winter tires that are due to be replaced next winter season. A friend of mine has a set of 205/ 60/ R16 winter tires that were used for only 2 months before he replaced his vehicle. Would they work on my van?

Editorial Comment:

If your friend had a pair of dress shoes sized 9 which he used only once or twice and you wear a size 11, would you be thinking about wearing his shoes?

This, essentially is what you're facing here ... putting smaller tires on your vehicle. Our Tire Size Calculator would show you that his tires are over 6% smaller than what you are now using. This would lead to an appreciable error in the speedometer reading and an increase in fuel costs. It is not usual for a size swap to be recommended if it exceeds 2% from the original size unless you are prepared to experience significant changes.

I do not recommend this change. A 205/70 or 235/65 using 16 inch rims would be better suited for your 2013 Dodge Caravan.

Will 195/65r15 tires fit 2001 Pontiac Grand Am rim?

by Randy
(PG, Canada)

I was recently given a new set of 195/65r15 all season tires off of a 2009 Toyota Corolla. I have a 2001 Pontiac Grand Am SE, which runs on 215/60r15's. I know the bolt pattern for the two cars are different, but I was wondering if I could have the 195/65r15's mounted onto the stock 2001 Grand Am rim? I haven't been able to find anything online that says yes, they can be or no, they can't be.

Replacing 225/70R15 with 235/75R15

by Felix
(Barnegat, NJ USA)

I have a 2009 Ford Ranger, regular cab Sport w/rear wheel drive. The tires need to be replaced. I have 2 almost new tires from a previous vehicle which are 235/75R15. I would like to know if I can use them on my Ranger which currently has four 225/70R15s.

Editorial Comment:

Without even doing any calculations, or using our Tire Size Calculator (see link below) I feel that this is not a good swap. The rule of thumb in selecting a new size is that if you increase one of the first two numbers, the other number should decrease (or at least stay the same depending on the amount of change in the first number). So this one is increasing BOTH numbers and that makes me feel uncomfortable.

It turns out that there is a 5.3% increase in size in the 235/75R15's which is far beyond the limit of 2% difference which is usually recommended for an equivalent swap.

Apart from that, even though you may keep the larger tires on the same axle (never mix sizes on the same axle), which one are you going to carry as a spare? Or do you want to carry a spare for each size?

Generally speaking I do not consider mixed sizes on a vehicle to be very practical.

Will either of these snow tires fit on 2013 Ford Focus?

My 2013 Ford Focus SE has tires 215/50R17. Will snow tires 215/60R16 mounted on 16 inch rims fit? Or snow tires P215/60R16 mounted on 16 inch rims?

Editorial comment:

In terms of size, there is no difference between a 215/60R16 and a P215/60R16 tire. The "P" is simply a designation added to some tires to show that they are designed according to American standards for Passenger vehicles. If the "P" is missing it may be using European standards. In some instances the load and pressure characteristics may be identical but usually one tire may be safely interchanged with the other.

The 16 inch tires you are thinking of using are just slightly more than a 2% difference bigger than the original tires. Normally tire professionals do not recommend a difference of more than 2% when substuting tire sizes.

The only other issue you need to be aware of is the bolt pattern of the wheels because these may differ. Also, I am not sure if your vehicle is designed to operate with 16 inch rims. If it is not you may have issues with the rims being too small for the brakes which fit inside the wheel.

p225/60r17 as replacements for p235/65r 17 tires

Can i replace p235 / 65r 17 with p225 / 60r 17 tires?

Editorial comment:

Whenever considering changing to a different sized tire a general rule to keep in mind is that if the first number changes, the second number in the size should change in the opposite direction by half as much.

Of course, this isn't a hard and fast rule, but if the two numbers are not going in opposite directions, the chances are that the difference in sizes are going to be too great to result in a good swap.

That is my first impression, when I saw your size numbers. Now, use our Tire Size Calculator to get the details and see the actual effect.

In your case there is a difference of over 4%, the 225/60 r17 tire being that much smaller that what you started with. By our experience, I don't like to recommend a difference of over 2% for optimal results. So, I would not recommend this change.

what will tire size make a difference

by Migel Guevara
(Hollis, Oklahoma)

my 2005 chevy colorado calls for p 225/75 R 15 size tires i bought a set of 4 size 185/60 R 15 tires how much will this change my speedometer will it slow it down or speed it up and how much difference will it make 5,10,15,miles faster to maintaine speed limit or slower

Editorial Comment

I really hope you are not serious about using these tires on your Chevy Colorado, or that you made some kind of error in typing in the tire sizes.

The difference between a 225/75 R15 tire and a 185/60 R15 is enormous and I don't believe that you will even be able to mount the 185 tire on the rim which the 225 tire uses, because it is considerably narrower. Even if you do succeed in mounting it, I highly discourage you from using it because it may come off with even slight lateral force in the tire, such as you might experience in making a sharp turn.

The 185 tire is considerably lower: more than 4 inches, and this may cause frequent bottoming-out and loss of clearance in your vehicle. There will be a difference in your speedometer reading of more than 16% which means that when the speedometer shows you are travelling at 100 your real speed would really be less than 85, and you will use that same amount of extra fuel in using these tires.

I definitely do not recommend you use these tires as a substitute for the original ones.

Replace P215 55 R17 with P215 50 ZR17 tires

by Jose Rodriguez
(San Juan Puerto Rico)

i have a 2010 toyota camry se v6 the tire who came with the car are P215 55 R17 i want to know if i can replace with a P215 50 ZR17 tires

I WANT TO KNOW IF I CAN REPLACE THE TIRES WITH THE OTHERS

Editorial Comment:

Of course you can replace one sized tire with another. The question you need to ask is what will happen if you do this and then decide if you want the consequences.

Going from a P215 55 R17 tire to a P215 50 ZR17 tire means that you are putting a lower tire (the 55 is less than 50) on your car. The difference is 5% of 215, so the new tire will be about 11 mm lower which isn't a great deal of height, but you need to ask yourself if you are driving over roads where the loss of about 1/2 inch of height will cause any problems.

Putting a lower (smaller) tire on any care will cause you to use a bit more fuel because the tire will not travel as far for each time it makes a full revolution and your speedometer will be wrong showing that you are travelling faster than you really are. Check our tire size calculator to see the exact differences.

If you can live with these differences, then you will be OK making this change.

Upsize tire height

by Al
(Costa Rica)

2007 Ford Explorer

2007 Ford Explorer

Is there any effect (other than Speedo) when upsizing the tire with AWD ? 245 65 R17 OEM with 245 70 R17 OEM width but taller. Ford explorer sport track 2007.

Editorial Comment.

Yes, there are other effects to changing the tire size apart from the difference in speedometer reading which you can expect.

When you switch to a larger diameter tire you can also expect to use less fuel because with each revolution it will carry your vehicle slightly further, and perhaps for the same reason you could expect to have the tires wear out slightly slower. The estimated difference in both of these is the difference in tire diameter, which in the case of going from 245/65/R17 to 245/70/R17 is 3.27%.

This difference is slightly more than I like to recommend (I like to see people stay within 2% of the original size), but as long as you aren't running into a difficulty with the tires rubbing, or causing your engine to strain because of a lower power transfer, you may want to go with this swap.

If you want to stay within my guidelines, look for a 225/70 or a 235/70, for a higher tire and 255/60 or 255/65 if you'd like wider treads.

Tire Concerns: 195/70R14 vs 185/65R15 tires

by robert
(sault ste marie, on, canada)

i have a 2001 chev cavalier 4 door sedan that has 195/70 r14 tires. I was given 185/65 r15 tires will these tires fit on my vehicle if i buy winter rims to fit on these new tires. Is there any concerns buy using these new tires.

Editorial Comment:

Possibly without even being aware of it you have followed the basic adjustment rule that is used in Plus Sizing: that is reducing the tire size to compensate for the increase in the rim size.

These 185/65R15 tires are darn close to a good match for your original size, now all you need is to get the right rims for you car. The key to getting the right rim is the size of the centre hole and the number and spacing of the bolts to match those on your original rims. With most popular cars this isn't difficult if you buy from an experienced wheel dealer, you simply tell them the vehicle you want to use them on and they will give you a selection to choose from. Other than that you can often search the offerings of on-line rim sellers and they will give you the specs. for your car that you can then use to specify the size that you need.

How do 31x10.50R15 tires compare with 245/70R16 or 215/80R16?

by Emma
(Wales)

We have just bought a 2000 Trooper to replace our 83 Pajero, the tires on the Pajero are really good 31x10.50R15 ones and we wondered if we could use them on the Trooper? The trooper currently has 245/70R16 tires on it but the book says it also takes 215/80R16.

Editorial Comment:

First note that your Pajero had 15 in wheels and the Trooper uses 16 inch wheels so right from the start you won't have a fit unless you change wheels, too. You cannot EVER put a 15 inch tire on a 16 inch wheel!

Forget it!

P255/65R18 tires for 2011 Dodge Ram 1500 Sport

by Ty
(Canada)

I have a 2011 Dodge Ram 1500 Sport and I want to mount my P255/65R18 tires that I just bought last winter. (Don't have that other vehicle anymore and I don't want to just get rid of these (almost new) winter tires).

Editorial Comment:

Since you didn't specify the size of tires your Dodge Ram now uses, I can only start by supposing that it has what is listed as OEM, which is 275/60 R20.

Using our Tire Size Calculator to compare these two sizes, I would conclude that this is not a good match, because the 255/65R18 tire is nearly 2 inches smaller in diameter and that works out to a 5.88% difference in size. I never recommend a swap of more than 2% difference in sizes.

Apart from those considerations, you should be aware of the load and speed ratings in the alternative tires to make sure they are compatible (the same or greater) than your original equipment. Because this suggests a different sized wheel, there may be issues which may influence clearance with the body work and suspension, so it is important to test the new wheels and tires carefully for proper clearances before committing to their use.

Replacing Tires with Odd Sizes

1994 Toyota Camry

1994 Toyota Camry

I have a 1994 Toyota Camry LE with P205-60 R15 tires on it. Can I put two P215 75 R15 and two p205-75 R15 tires on it to replace the old ones? The four odd sized tires were given to me by a well meaning friend.


Editorial Comment

My first inclination is to ask if your "well-meaning" friend might be meaning to play a practical joke on you by complicating your life.

If I wanted to help out a friend, I doubt if I would give them tires which are far too big as a substitute for the tires they need to replace. Even the smallest of these tires, the 205/75 15 tires are nearly 10% larger than the original tires. This is way beyond the 2% difference limit which I like to recommend.

It would be impossible for me to say for certain without actually doing a test fitting whether or not these tires would actually rub against some area of the car in use, but because of the size difference, I would not be surprised.

Another complication is using different sized tires on a car. Sometimes this may be acceptable as long as you don't mix the sizes on the same axle, because if you do you could have serious control and safety issues.

Also remember that you also have a spare tire which is still the original size. If you have a flat and put that into use, you'd then have 3 different sizes in use and that would almost certainly create a hazard in terms of being able to control your auto at virtually any speed over a crawl.

At least try to swap these free tires for others which are the same size or much closer to the size you now have on the car.

215/65R16 tires for 2012 equinox

by Adam
(Canada)

Will a tire size 215/65R16 fit onto a 2012 equinox.

I have just bought a 2012 equinox and I have a set of winter tires on rims and would like to know if they will fit. The tire size on the equinox is 225/65R17. I know the winter tires won't fit onto the equinox rims but I do have them on rims with the same bolt pattern. Any information on this will be greatly appreciated.

Editorial comment:

If, as you say, the bolt pattern on the 16 inch rims is the same as on the 17 inch rims, there may not be any problem with the tires fitting, because they are smaller. This, in itself, may not present any problem.

But, there may be a problem with brake components or other issues because of the smaller rims.

There is another issue concerning the TPMS (Tire Pressure Monitoring System). If you have a TPMS on a vehicle and attempt to install wheels or tires which are not calibrated with functioning sensors, some areas have made this illegal and no reputable dealer will install them for you.

I hope these thoughts help.

Tire Concerns; Do 225x 85 tires fit a '99 town and country?

by jess
(lodi, ny)

I have some very good used tires and hope to use them on my minivan that has 215 x60 on now. might they fit on the back? This T+C has much rust on the strut support tops, needs a muffler and I don't/can't want to spend much on it if it wont last.

EDITORIAL COMMENT:

The first thing you need to do before you even start thinking about switching one size of tire for another is to make sure that they both fit on the same wheel!

Since you've told us that you have a 99 Town and Country van, I can discover that the original tire for that vehicle was a 215/60 R16. What I don't know, is the size of the wheel the 225/85 tires you say you have uses.

As far as I know, there is no 225/85 R16 tire currently made, which suggests that the tire you have is for another sized wheel. If this is the case, forget it right from the start unless you have the wheels to go with it.

In any case --if the tire you have actually is for a 16 inch wheel, our Tire Size Calculator shows that this tire would be far too big to be an acceptable alternative for the original tire.

Increasing tire size

by wendy
(laconia,nh)

can i replace my 215/60/r15 tires with 215/70/r15 tires on a 2003 oldsmobile alero gl?

Editor's comment:
The fundamental thing you need to realize when you think about changing tire size in any vehicle is what the numbers mean in the size. The first number is the width in millimeters. It doesn't really matter what the units of measurement are if you simply remember that if the number increases, the tire is wider; if it decreases the tire is narrower.

The second number is the Aspect Ratio, and is used to calculate the height of the tire's sidewall. The AR is a ratio so if it increases, again the tire is going to be higher, if it decreases it will be lower.

Under normal circumstances, whenever anyone is wanting to use a different size on their vehicle because one size is cheaper, or maybe easier to find, or has a nicer "look", we try to look for a size that ends up with the overall size of the tire doesn't change more than about 2%. This can often be done by following the rule of thumb that says: If you increase one of the numbers in the size, the other one should decrease so that there is a minimal effect of the change.

In your case you are increasing the second number to 70 while the first number remains the same. Then end effect is to increase the size of your tire by about 6.7%, and this is much more than the 2% range we like to recommend. Two options that meet my requirements are 205/65R15 or 225/55R15.

I don't know if either of these sizes will meet other requirements you might have, in terms of look, price or availability. The 205/65R15 is a bit narrower, and the 225/55R15 is wider and because of this might not be suitable for your vehicle ... I'd advise a test fitting to make sure that it doesn't rub anywhere before making a final commitment to buying that size.

I hope this helps you in deciding what to do.

Tire Concerns: tires change to smaller size

I had on my car and 13" wheels some tires 155/80/13.
When changing to winter tires, in my shop I can get only 155/70/13 tires.
What are the effects of this change on my car?
Does this the consumption increase?

Comment:

Use our Tire Size Calculator to compare these two sizes and you'll see the 155/70 tire is smaller and the calculator will show you the differences to expect.

Actually a much more common size in many ares is the 175/70 13 and this is almost an exact match for the 155/80 13 tire and a size I would much rather see you use in place of your existing tire.

225 75R16 tires for 2013 Suzuki Grand Vitara

by Dan
(Winnipeg Manitoba Canada)

WIll 225 75R16 tires fit a 2013 Suzuki Grand Vitara Ltd?

I need to know if I can get rid of my stock 225 60r18 and put on 225 75r16 so I can get some proper off road tires.

If I can, I need new rims 16". What are the specs of the rims that I need? Backspacing, bolt pattern, etc....

If I can get the tires I want in 225 75r16, will there be any rubbing anywhere or would it just fill in the wheel well better.

I would like to put on Goodyear Duratracs rather than the Dunlop AT30 or 20's (I can't remember).

Editorial Comment:

Your best size to make sure you don't have problems with rubbing, etc. is 225/70R16.

The bolt pattern you need is 5-114. Offset will likely be between 30 - 40 mm. As long as it's close to this don't worry.

I don't recommend any particular wheels, there's a lot of variety available so check around and find something you like.

Send us a pic when you've made your choice.

I want to put bigger tires on my 1995 ford ranger's 14 inch rims.

by Randy
(Tempe, AZ)


what are my options? the original tires are 195/70R/14 but on other sites they say I can go as large as 235/70/14 but then other sites say you can only put on what is on the door sticker. I am confused...

Editorial Comment:
In theory you can put on any size of tire that will fit on the rims and within the space available in the wheel wells.

Now, just because you CAN do it, does not mean you should do it.

Keep in mind that as you increase the width of the tire from 195/70R14, the first number is telling you the width. The second number is the Aspect Ratio (AR) which helps you calculate the height of the tire. If you increase the width and the AR is the same, your tire is not only getting wider but it is getting higher, too.

When the tire gets higher, it is bigger and this affects your performance because with each turn of the wheel the vehicle goes a greater distance. This will affect the amount of power which reaches the wheels, the reading on your speedometer and the gas mileage which you get.

Many professionals recommend that if you want to change the tire size that you try to find a size that has pretty much the same total diameter so that you don't change the performance which the vehicle was designed to give.

You can use our Tire Size Calculator to find different sized tires which will stay within a given range to keep you on the safe size, or ask a tire specialist about Plus Sizing if you want to change wheel sizes. We also have an article on that.

CAN I USE THIS TIRES ON MY 2011 GMC TERRAIN
bfgoodrich advantage 98t trot 235-55-R18

I HAVE MICHELIN NOW TO EXPENSIVE THA WHY I WANT TO GET BF

ED. COMNT:

DNT DO MUCH TXT BUT IF SIZE IS RITE THEN BF GOOD TO.

Come on folks, if you want advice for free, please give me enough details to provide you with a decent answer. You want to try a different sized tire? Please tell me both the size you're using now and the size you want to use. If you want to compare different tires, tell me what you're comparing them to. (Michelin and BF Goodrich make many different sizes and tire designs).

My advice is only is as good as the information you give me to work with and if you don't give me enough to go on chances are I won't even provide an answer.

And, if you aren't aware of it, typing in ALL CAPS is not the best way to get anyone to want to give you friendly assistance.

215/70R15 compared to 215/75R15 tires

by Carla
(Toronto, Ontario, Canada)

2001 Chevy Ventura

2001 Chevy Ventura

I have a 2001 Chevy Venture Warner Bros edition. My current tires are 215/70R15. My mechanic has a good price for slightly used 215/75R15 tires. He says it will be fine to up them by 1/2 an inch. Can you advise if this is a good move for me, or if I should just stay with my current size? What change can I expect from my speedometer or gas usage if I change the tire size?

Editorial Comment

Just so you understand what's happening, when you go from a 215/70R15 to a 215/75R15 tire size, you are, in effect increasing the height of the tire by 5% of its width. (75 - 70 = 5) So 5% of 215 is almost 11mm or .42 inches.

It may not seem like a great difference, but it is making the tire 3.15% bigger in diameter. This will produce an error in your speedometer of 3.15% and a decrease in your fuel consumption of the same amount. Your speedometer will show that you are going slower than your actual speed, so if you have a habit of travelling at exactly the legal limit, you will be speeding all of the time.

I normally do not recommend a difference of more than 2% in tire size unless you are wanting to experiment or are fully prepared to accept the consequences of operating your vehicle beyond what it was designed to do. So long as these tires do not rub in any place the change will not produce any disastrous consequences as long as the larger tires are equal or above the speed and load ratings of the ones they are replacing.

Tires 215/65 R16 to 235/60 R16

by Robert Peralta
(Salmiya State of Kuwait)

I had Sportage 2008 model. Currently I am using 215/65 R16 tires & planning to change my tires to 235/60 R16 on the same rim. Is it possible?

Editorial Comment:

Of course it is possible, but the question you need to ask is "Is it practical?" or "Is it a good idea?"

Actually, in answer to both those questions about switching from 215/65 R16 tires to 235/60 R16, it seems like a pretty good fit in my estimation. Using our tire size calculator shows that the new size is only slightly larger in over all diameter and this is good.

The only possible concern comes from the wider width of the tires because in some vehicles the space available in the wheel wells may cause some problem. Try a test fitting if you can and be especially careful in the steering wheels to try turning the wheels to the extreme left and right sides to make sure there is no rubbing there. If this passes, you'll likely have no trouble with this change.

225/55r17 on 1998 mustang gt

1998 Mustang

1998 Mustang

I have a 98 mustang gt. My tires are bald i came across some tires they are 225/55r17 and the tires on my mustang now are 245/45r17. can someone help me?

Editorial Comment

The recommended 17 inch tire for a 98 Mustang GT is 245/45R17 while a plain mustang uses a 255/45-17 which is slightly larger than the tire you want to use. As it stands the 225/55 tire you wish to use is about 1/2 inch larger in radius or about an inch bigger in diameter than what you now have.

I'm not familiar with the details of the difference in the amount of clearance which the GT and the plain Mustang from 1998 have so I'd caution you to pay attention to this detail, perhaps with a trial fitting if you can't clearly determine how much space you have to play with in you wheel wells.

155/65/13

by Bob
(England)

Ok the girlfriends front passenger tyre is flat. The spare in the boot is a 155/65/13 but all others on the car are 165/65/13. is it ok to put this wheel on while we get the flat one fixed as the rim size and side wall height are the same? Or would I need to put another 155 on the drivers side too to be legal to drive. Last thing we want is to crash and have invalid insurance due to a tyre sizing problem.

Editorial Comment:

A spare tire of 155/65 r 13 which is slightly different in size from the rest of the tires on a vehicle is of no great concern, especially if that tire is used exclusively as a substitute for the regular tire.

The actual difference in tire diameter is only 13mm or 1/2 an inch which is a difference you could conceivably find between a new tire of that same size and one which has been used for some time. Especially if the rest of the tires have been worn down the degree of difference in the spare will be even less, if it is still relatively un-worn.

If you did want to use this alternate tire permanently, you'd be best to install another tire of the same size on the same axle, so that you are not mixing sizes. This primarily applies to a stander 2 wheel drive vehicle; many 4x4 vehicle warn drivers not to mix any tire sizes for the reason of avoiding possible mechanical damage.

will 235/75/17 tires fit my envoy?

by Doug
(cambridge ontario)

i got 3 235/75/17 tires for $90 and I'm hoping they will fit my 2002 envoy?

Editorial Comment:

Good luck in getting an answer to your question. There are different models of the 2002 Envoy and I have selected, arbitrarily, the 2002 GMC Envoy 4wd which normally comes equipped with 245/65R17 tires.
The OEM tire for this model is lower (65 vs 75 AR). In fact, the tires you've bought are 4.5% bigger than the OEM tires for the vehicle I've mentioned and this is more than the 2% maximum difference that tire specialists like to recumbent when changing to wider or narrower tires.

You will definitely experience a change in speedometer reading and fuel consumption of about4.5% with these tires and it concerns me that you only have 3. It is never a good idea to mix different sized tires on the same axle except for temporary emergency use, so I would only like to see you use two of these on the same axle, keeping the other as a spare, or buy another one so that you can have all 4 positions with the same sized tire.

Biggest tire for Mitsubishi Montero Sport

by Jimi
(Bourbonnais, Il.)

2008 Mitsubishi Montero

2008 Mitsubishi Montero

2008 Mitsubishi Montero
Low profile wide tire
High Profile tire
Extreme 40 inch rims

I have a Mitsubishi Montero sport ls and I was wondering how big of a tire I could put on it. Something nice and beefy. Off road or mud tread.

Editorial Comment:

You didn't mention what year of Mitsubishi Montero Sport you have so it might be a different case for different years, but from the photos I've seen there has been a general consistency over recent years in terms of the amount of space which is available in the wheel wells. I've added a photo of a 2008 modle which I suspect is quite representative of what you might have.

I can't give you a definite answer to your question, but I will offer you a few comments which may help you in choosing what will be best for you. Click on each of the thumbnail photos above to see a larger version of the photo.

Notice that there seems to be a generous amount of space in the wheel wells, which is not something that all vehicles offers. In this sense you may have a lot of latitude to work within.

At the same time, you need to keep in mind that when we are asked about different tire sizes for vehicles, we usually recommend that customers avoid making changes which are greater than 2% bigger or smaller than the OEM size. The reason for this is that it creates a speedometer error, affects fuel consumption, and will change the amount of power that is transmitted from the power train to the wheels. If you increase the overall diameter of the tire (not the rim size) by too much you may seriously affect the performance of your vehicle.

What does this mean in practice? Well if you put on a wider tire, you need to choose one which is a lower profile, or if you install a tire that is taller, then you will subtract the width of the tire. Read our page on Plus Sizing to learn more about this.

All of the above assumes that you will be staying with the same sized rims on your vehicle. If you change the rim size, the same principles also apply but you also need to take into consideration the effect of the change in rim diameter and how that will affect the total diameter of the tires.

When you are considering wider tires, you also need to realize that every tire is designed to be mounted on a certain width of rim but a certain degree of tolerance is allowed (usually about 1 to 1 1/2 inches is the maximum variation tolerated.) So, if a tire which appeals to you is more than 1 1/2 inches wider than the OEM tires that you now have, you will probably have to consider getting wider wheels in addition to the tires.

A final option you might have is to put very large sized rims on with very low profile tires.

In the end, no matter what you choose, the only way you are going to know for certain whether of not your choice will work is to mount them on your vehicle and try it under different conditions, road types and in tight turns to the left and right. If possible I'd recommend a test fitting before you commit yourself to making a purchase.

Good Luck

Lt 275/65/r18 for mazda CX7

by Les
(Billings, mT)

I have a 2007 Mazda CX7 Stock tires are 235-60-18 Will 27/65/18 fit, on This?

Editorial Comment:

I doubt very much if a 27/65/18 tire even exists, let alone be suitable for a Mazda CX7.

Now, a 275/65/R18 is more credible as a tire, but even that --at first glance doesn't seem like a good tire to swap because BOTH of the first two numbers in the size are larger than the originals.

My quick-n-dirty rule is that if one number increases then the other one should decrease (or possibly stay the same).

Our tire calculator, shows that there is a difference of more than 10% between the overall diameter of the two tires and the generally accepted difference for a satisfactory size swap is no more than 2%.

A much better choice, if you want a wider tire and you have space in the wheel well would be a 245/55 or 255/55 in the same diameter.

Can I replace 205x70x15 with 205x65x15 tires

by Burleigh Martin
(Augusta, Maine)

205/65/15

205/65/15

I have a 2001 Honda CRV and the tires that are on the car now and need to be replaced are 205x70x15-- I have found a good set of used tires with almost new tread but they are 205x65x15- So my question's are can I swap the tires and if so what would happen to the car if anything


Editorial Comment
The swap you propose from 205x70x15 to 205x65x15 is beyond the range I normal recommend. You would be going to a smaller tire which is just over 3% smaller than the original. This will result in using more fuel and your speedometer showing a speed more than your actual speed.

My normal limit is a 2% difference so I do not recommend this. Granted the difference is not great and you might accept it, but it is not one which I like to see.

can i put 235/75/r15 on the front of my all wheel drive ford explorer with 235/75/r15 on the back and drive it without messing up my transfer case?

1997 Ford Exporer

1997 Ford Exporer

I have bigger tires on the back of my 1997 ford explorer (225/75/r15) and smaller tires on front, it grinds when i drive. if i put 235/75/r15 on the front and keep the 225/75/r15 on the back will it drive without messing up anything? is that too big of a size difference for an all wheel drive?

Editoria Comment:

I'm not familiar with the details of all the 1997 Ford Explorer tire specification, but it seems rare to me that some version of this vehicle would have different sized tires on the front and rear. This may be the reason why you are hearing a grinding noise and in fact you may have already had damage to your vehicle. Most 4 wheel drive vehicle are designed to use the same size tire on all 4 wheels. Please check out the OEM requirements for your specific model.

The 97 Ford Explorer 4wd came with two different options for tires 225/70r15 and 235/75R15. It sounds like during its life there may have been some confusion about which size was OEM for your vehicle, but I doubt that it ever was designed to have two different sizes on the front and back.

There is likely a sticker on the driver's door post or possibly inside the glove compartment which specifies the original tire sizes and pressures which were to be used with your vehicle.

p215/65r17 for 2005 Chev Trail Blazer

by Ryan
(canada)

Will firestone p215/65r17 fit my 2005 chev Trail blazer

Editoria Comment

Certainly the size 215/65R17 will "fit" on a 2005 Chev Trailbalzer but since the recommended size is 245/65R17 I wouldn't want to try it because it is much narrower and also, as a consequence somewhat lower than the recommended size.

You do want to make sure that the load/speed index of the tire is at the least 105S or 105H. If it is less you're asking for problems, if it is more, there's nothing to worry about. Most of the 215 tires I've seen in this size are rated at 98 or 99.

Tyre Size 215/70R16c

by Ranjit Chaudhuri
(Abu Dhabi , UAE)

We bought an H1 Van made by Hyundai. The tyres used on this vehicle has a size 215/70R16c . The dealer says that we cannot use a tyre 215/70R16 Radial on this vehicle Hyundai H1 Van and have to use a 215/70R16c only . Why is the "c" so important ? Who are the manufacturers of this kind of tyre ?

We are all perplexed because the only company manufacturing the tyre with a "c" and in stock is Hankook and the tires are very very expensive. Are we being misled so that the dealer can make a bigger profit?


Editorial Comment:

The only place I have noted the use of the letter "C" following a tire size is to designate the load range of trailer tires, which are not suitable for use on a vehicle, or on light truck tires, which may be suitable. If this is the case, you could use tires with a higher load range like "D" or "E" but those would likely be even more expensive than the C range. In any case you would not ever want to use anything lower (such as "B").

It could be that this is the only kind of tire which your dealer has available for your vehicle but that doesn't mean that you can't switch to another manufacturer and get satisfactory results.

In the first place, unless there is some special situation where you live, no vehicle's warranty or performance is affected by the brand of tire which they use. In some countries, the importer of the vehicle actually changes the brand of tire from the one installed in the factory for business reasons that have nothing to do with the manufacturer.

The things you need to watch for when you are changing tires is to make sure that you have a size which is close to the original size recommended by the manufacturer. My recommendation is to not change to any tire which is more than 2% larger or smaller. Next, make sure that the load rating -- that is the amount of weight it is designed to carry is equal to or greater than your original tire, and that the speed rating is equal to or above that maximum speed which you are likely to drive.

If you keep these two points in mind, and ask a reliable tire dealer to assist you should be able to change to different tires that will serve you well without experiencing any problems.

Tire Concerns: do all saturns use tire size 195/60/15?

by Maria Elena
(Temecula, CA)

I am planning to buy a used 2002 saturn and would like to know if all saturn station wagons use same size tire.

Editorial Comment:

It is quite common for certain brands of cars to change tire and wheel sizes from one year to the next, while others may continue to use the same sizes fro several years in a row.

It is even common for cars of one make to have different tire and wheel sizes depending on what country they are sold in so if, you might have had a certain car in one country you could go to another and find that the same car uses a different size.

The only way to know for sure is if you were to specify what year and model of Saturn you want to compare to another and then try searching for a tire for that vehicle at an on-line shopping site like tirerack.com.

Does tire size matter-- much

by Rick
(Allentown)

I have a 2002 Chevy S10 2 wheel drive with a wheel base of 4600. My factory tire size is 205/75/R15

Can I use a 235/70/R15 will there be any problems if I use this size?

Editorial Comment:

To begin with, you might note that in the 235/70 tire you have a wider tire but by reducing the aspect ratio from 75 to 70 you are partially compensating for the extra width so that the height of the tire is not as high as it would be if you had used a 235/75 tire.

Check on our Tire Size Calculator and you'll see that the increased diameter is 0.85 inches which represents an increased size of about 3.12%. This may not seem like a large difference, but it is beyond the limit of 2.0 which experienced tire people generally recommend for best results.

With this difference in size you will see that you speedometer will show a speed which is 3% lower than what you are actually travelling and your fuel consumption will, under ordinary circumstances, drop by that same amount, provided that you are not driving more in lower gears to make up for the lower power transmission which reaches the road.

Will 195/65r15 tires fit 2001 Pontiac Grand Am rim?

by Randy
(PG, Canada)

I was recently given a new set of 195/65r15 all season tires off of a 2009 Toyota Corolla. I have a 2001 Pontiac Grand Am SE. I know the bolt pattern for the two cars are different, but I was wondering if I could have the 195/65r15's mounted onto the stock 2001 Grand Am rim? I haven't been able to find anything online that says yes they can be or not they can't be.

Editorial Comment:

Based on the information you have given the answer is: Maybe.

If you would have simply stated the size of the tires that are currently mounted on you 2001 Grand Am it would be easier to give you a possible answer. Simply stated, the OEM Grand Am Pontiac sold in 2001 was offered with both 15 and 16 inch rims. If your vehicle now has 16 inch rims, there is no way you can mount 15 inch tires on them.

From what I can determine the OEM size for 15 inch wheel was 215/60 so the rim diameter might not prove to be a problem except that all tires are designed to be fitted on a rim of a certain width. There is a certain degree of flexibility in their design, so that you can use rims which are slightly wider or narrower but only within about a 1 to 1 1/2 inch range.

In your case, if you have 15 inch rims you are looking at mounting a 195 wide tire onto a rim designed to carry a 215 tire (the difference in width being almost one inch). This could work but it would be best for you to get the specs from the tire manufacturer and learn if the tire is allowed to be used on the width of the rim you have on the Grand Am. This width is usually stamped somewhere inside the rim.

will 205/65R15 work on scion xa

Want to buy rims with 205/65R15 on the i have P185/65R15 on my current rims now on my scion xa.


Editorial Comment:

You didn't give much informations about your Scion XA, so I'm only basing my comments on the assumption that this might be a 2006 vehicle which has 185/60R15 listed as the OEM size.

On this basis you may find problems because the tire you want to use is not only wider but higher and this could produce problems with clearance space.

The tire you propose to use is more that 7% larger than the original and I seldom recommend anyone go more than 2% difference. Also you need to make sure the wheel lugs match with the new rims and that the speed and load rating of the new tires is at least equal or greater than what you've been using successfully up to now.

what is difference between 215/60r16 and 215/75r16

by Louis Bailoni
(Plains Pa.)

I have a 2006 sonata with 215/60 tires and they always look low. so my question really is what is difference between 60 and 75 and also what tire can I put on that will not look like it is going flat.

Editorial Comment:

The 75 series tire is a higher tire then the 60 series. These numbers are called the Aspect Ratio (AR) and you use this number, as a percentage, to calculate the height of the tire's sidewall from the width of the tire (215 in your case). As you can see, without even doing any calculations 75% will be a larger number than 60%, so the 75 series tire will be 15% higher than the smaller tire.

Often this difference will be too big for the space available in your vehicle and the difference in size also creates other issues, such as an error in your speedometer reading and the fuel which you will use.

Our Tire Size Calculator will calculate the exact differences if you want to compare these two sizes. What we recommend, however, is to stay within 2% of the original tire size for the best results.

P205/65 R15 vs 195/65R 15

2009 Honda Accord

2009 Honda Accord

My brother wants to give me some tires from off his old Accord. They are P205/65 R15 and my tires are 195/65R 15. Can I use them?


Editorial Comment:

You didn't tell us the model or year of the Accord, not did you specify the make, model and year of your car. Yes, Virginia, it can make a difference. So, please take anything you read from here on with a grain of salt … it is possible that it may not apply in your situation.

P 205 tires are slightly wider (10mm) than 195 tires. For most cars and wheels this would not make any significant difference.

The fact that the aspect ratio (AR) is 65 in both cases results in the 205 tire being slightly higher than the 195. How much? 65%. of the difference in width, or 6.5 mm. This is about 1/4 inch and should not amount to any concern in most vehicles either unless one of them has extremely limited space or engineering tolerances.

I'm guessing, because of the very small differences that you could use the other tires without any problem but there is a verrrrry slim chance that they would present some problem.

Good luck, next time give us more details and we can ignore those we don't need, but you're leaving it to chance that we'd guess the right ones if you don't.

P215/65R16 to replace P225/60R17 tires

by KL
(San Jose, CA, USA)

2011 Toyota sienna

2011 Toyota sienna

I have a Toyota Sienna van that now has P225/60R17 tires on it. The tag on the door sill states two tire sizes - P225/60R17 and P215/65R16. Are these two tires interchangeable? Will the P215/65R16 fit my current wheels which should be 17"?

Editorial Comment:

Your Toyota Sienna van does what many car makers have done for many years: it offers different sized wheel options when the car is assembled at the factory.

If you were to calculate the overall diameter of the two tires shown on the door sticker, you would find that there is very little difference between them. In your specific case, you'll find that there is 2.23% difference between the 16 inch tires and the 17 inch ones.

You will notice that the Aspect Ratio, which is the second number, is smaller in the 17 inch option. This is done so that with the increased width of the tire, the sidewall height is lowered to compensate for the larger rim diameter.

You absolutely do not want to attempt to fit 16 inch tires on the 17 inch rims that you now have. This is likely to be extremely difficult, if you could even get them to pass over the rims to install them. And, if you were going in the other direction it would be, in addition, dangerous; not only in the installation but in the use of the vehicle, too.

In your case you can think of this as you wearing size 10 shoes and trying to wear a size 8 shoe. It just won't work. Don't try it.

If you wish to go for the other size you'll need to change a 5 wheels (remember your spare tire too).

225/55/17 for 2010 Toyota Camry

Can I replace 215/55/17 tires with 225/55/17 on a 2010 Toyota Camry se v6?

Editor's comment:

The difference between 215/55R17 and 225/55R17 tires is very little. Size wise there is only about 1.65% the 225, of course, being bigger in diameter, too.

You will realize practically no difference in speedometer reading and fuel consumption with this change.

The one thing you want to watch is that the load and speed rating of the new tire is at least as great or more than the original.

I'd expect you'd only have a problem with space if you have already been noticing some rubbing when turning or passing over bumps. If this has never been an issue, I'd say you're pretty well set with this change.

P205/50R15 Fit Honda Civic?

by Hamo
(Toronto)

Honda Civic Coupe

Honda Civic Coupe

I have Honda civic 2002, and I want to put some rims, please could you tell me if P205/50R15
84H will fit?

An optional tire for your vehicle in 15 inch is 195/60R15. If you go to a 205/50 R15 you will have no trouble in terms of space, with the possible exception of being too wide and that you should be able to confirm with a test fitting.

The biggest concern I have is that this tire is over 4% smaller in overall diameter and this will not only produce a speedometer error but will also result in an increase in fuel consumption by about the same amount.

If these issues are acceptable to you, you may want to go ahead with the swap, otherwise choose a size a bit closer to the 195/60R15.

Down sizing tires

by J Lee
(Canada)

Can I replace my summer tires 225/65 R16 with winter tires
215/65 R15?

Editorial Comment:

It's not clear whether you made a typo or not. Did you really intend to go from a 16 inch tire to a 15 inch one? If this is the case, the problem is considerably changed.

I would not recommend changing wheel size in part because you need to have an extra set of wheels (5 of them, because you need a spare, too), but also because the over all diameter of the 15 inch tire is well beyond the 2% limit I usually recommend for a difference in sizes. Also, there is the possibility that the vehicle you have was not designed to use 15 inch rims, so it is possible that this simply wouldn't work.

Now if you wish to switch from 225/65/R16 to 215/65/r16 tires, this is a viable switch. It says within the 2% difference in over all tire sizes and shouldn't present any major concern it performance or operation.

Tire Concerns:Higher Profile tire

by Todd Hall
(Flint Mi USA)

i have a 2010 ford focus ses sedan. three of my tires are bad but i cant stand the low profile 45 series. Can i put a 60 series tire on instead

Editorial Comment

The 2010 Ford Focus SES Sedan was also offered with a 205/50 16 tire as an OEM option, so it is likely that you may be able to find a higher profile tire in a 16 inch wheel, but this will, of course, involve the expense to switching wheels too.

If you go to a 60 series tire you will need to move to a considerably narrower tire than what you now have (for example a 175/60 16) so that you stay within a 2% range of tire diameter and not provoke any major performance issues with your car.

There are people who believe that you lose control capability with a narrower tire since you have less rubber touching the road, but some tire engineers report that while the contact patch gets narrower with a thinner tire, it also grows in length so that the total area of the contact area remains the same, provided you adjust the air pressure with the new tire.

This may have an effect on your rolling resistance and road noise, so unless you are prepared to experiment a bit with the outcome, you'd likely be better off not making such a radical change in your tires' profile.

can i mount 265/65R18 winter tires on my 2013 Cadillac SRX

stock tires are 235/65R 18 but would like to install a 265/65R18 winter tire. can this be done?

EDITORIAL COMMENT:

You may be aware that whenever you increase the width of a tire and the aspect ration (the second number in the size) remains the same, that you will also be increasing the sidewall height of the tire.

In this case the increase in sidewall height is 65% of the difference in width, which is 30 mm, giving an increase of 19.5 mm or 0.77 inches.

The result of this is to produce a tire which is a bit more than 1 1/2 inches larger in diameter. This is over 5% bigger than the original tire, and most people in the tire industry do not recommend changes of more than 2% unless you are prepared to accept significant changes in your car's performance and handling capabilities.

This is, of course purely theoretical, and you would also need to make a test fitting of the tire to make sure that it would operate without rubbing or obstruction. Apart from these considerations, you also need to make sure that the load and speed ratings of the proposed tire also meet or exceed the original specifications for your vehicle.

I do not recommend the size you are contemplating. If you want a wider tire you might consider a 245/60, 245/65, or 265/60 which are all within a 2% difference in overall size.

P225/60R/17 Tiresfort 2007 Honda CRV

by Leslie
(Bigfork, Montana)

I have found some used summer tires that are slightly smaller than my current tires which are 225/65/17. Will the smaller tires fit by 2007 CRV and will they affect the car's safety?

Editorial Comment:

Yes these tires are slightly smaller, in fact that are just over 3% smaller which is slightly more than the 2% difference I usually recommend when changing tire sizes. Your speedometer will read less and you will use about 3% more fuel because the wheels have to turn that much more in order to travel the same distance.

I don't think there is a safety issue unless the speed or load rating of the tires is less than the original tires. If that is the case, you should really consider another alternative. If the rating is equal or higher, then there is no problem.

Are tire sizes interchangable?

by Jenny:)
(NY)

I want to know if I can put a P205/50R16 or P205/40R16 on my 2007 Ford Fusion instead of the P205/60R16 that is currently on it (ford recommended size) and if I do what do I need to know before/after doing so.

Editorial Comment:

Asking if tire sizes are interchangeable is like asking if shoe sizes are interchangeable, but even more complicated.

Notice that a tire size has three numbers in it. Take the recommended size for the 2007 Ford Fusion: P205/60R16, for example.

The first number, 205, tells you that the tire is 205mm wide. The second number, 60, tells you that the height of the tires is 60% of the width, or 123 mm(.6x205). This is the distance from the edge of the rim to the tread of the tire. Finally the number 16 is the diameter of the rim, in inches, which the tire is designed to fit.

Because most vehicles have a limited amount of space inside the area where the tire is located, you need to be concerned about whether or not a different sized tire will fit in there without rubbing or affecting the operation of the vehicle. This varies with different vehicles, but if you are putting on a tire which is either higher or wider you need to be concerned with both these issues.

If the tire you put on is smaller, then as far as space is concerned the only issue is whether or not lowering the vehicle will cause a problem in the vehicle bottoming out when you travel over irregular surfaces or rough roads.

Changes in the overall diameter of a tire will affect the performance of a vehicle too. It will affect the speedometer reading, which with either show you travelling slower than you really are, or faster. This will also affect the power that reaches your wheels and the amount of fuel which the vehicle uses.

Normally, if the space issue does not present any problems, then we usually recommend that most people do not change the over all diameter more than 2% for the best results. Check out our Tire Size Calculator to compare different sized tires.

smaller diameter tires

by Ben Smith
(Kansas City,mo.64129)

Larger and Smaller Tires used to create sculpture

Larger and Smaller Tires used to create sculpture

my car uses a 215/50 R17 tire, I bought a set of 205/40 r17 tires, besides the speedometer being off, how will these fit?


Editorial Comment:

As a starting point whenever you are thinking about using a different tire size on any vehicle, use this rule of thumb: If one number in the size changes, one other number should change in the opposite direction. If that doesn't happen, chances are that the swap is not a good idea.

In your case you are starting with 215/50 R17 and planning to go to 205/40 r17. Because two numbers are both increasing, my first impression is to stop right there because it is going to result in a change in tire size which is too much to get optimal results.

Because the tire is smaller you will, of course have a speedometer error of nearly 8% but much more important, you will also be using about 8% more fuel. Depending on how much you drive that can be a considerable extra expense. If you now spend $100 a week on fuel, in only one year you would spend an extra $400 and it is likely those tires could last 2 years or more… are you saving enough in the bargain tires you're getting to make that worthwhile?

215/70/15 tires for Hyundai 2008 elantra

2008 Hyundai Elantra

2008 Hyundai Elantra

Will 215/70/15 tires fit Hyundai 2008 Elantra?

Editorial Comment

According to the specs I have available the OEM tire size for the 2008 Hyundai Elantra was 195/65 R15.

The tire you're asking for is both wider (205) and higher (AR = 70) than the original. Combining these two results in a tire which, overall is more than 7% larger than the original, and this is not a good choice for a tire swap because it will produce a significant speedometer error and may even lack space to operate properly. The fit, can sometimes work if you try a test fitting before, but I still do not recommend it.

Tire size

by Jonathan
(Alberta)

Just need to know if 245 60 r20 tires will fit on my 2002 ml320? Currently have 255 60 r17.

Editorial Comment:

The 245/60 R20 tire is about 8% smaller than the 255/60 R17 mostly because of the difference in the rim size. This will cause you to use more fuel and experience a significant speedometer error. I never recommend a size difference of more than 2% so this is far beyond the range that I would consider acceptable.

are 215/70r16 and 215/75r16 interchangeable?

by matt

215/75r16 are half the price. Are they interchangeable
on a honda element.


Editorial Comment

I would not normally recommend substituting 215/75 R16 tires for 215/70 R16 tires because there is more than a 3% difference is overall size and my "limit" is 2%. You would have an error in your speedometer reading but the good part is that you would use less fuel. If you combine this with a lower cost for tires that certainly makes them seem interesting.

More than anything, I would want to make sure that there is enough room in your vehicle to accommodate these slightly larger tires which are almost 1/2 inch (10mm) higher. Try a test fitting to determine this.

Tire Concerns; 185/55 R16 vs 185/60 R16 tires

by Andy
(Rochdale)

I currently have 185 55 R16 on my car and have been given a pair of 185 60 R16's is it ok to fit the 60's as a pair on the same axle as each other and am I correct in thinking that they will be just slightly higher ?

Editorial Comment:

Because the tires are slightly higher means that the performance of your car will be affected by this change. To discover exactly what these might be use our Tire Size Calculator to compare them.

Provided there is enough space under your car to allow these to be used without rubbing when you turn or when the car dips and the difference is within about 2% you shouldn't have any problem using them both on the same axle UNLESS you are running a 4X4 … in which case you need to have all tires the same size.

195/60R15 vs P205/65R15 tires

by Amanda
(Eureka, CA, USA)

I recently bought tires for one car then the head gasket blew. I'm wondering if I can put the new tires on my other car? The old car tires are P205/65R15 and my other car takes 195/60R15.


Editorial Comment:

You haven't made it really clear which tire is the new one and which is the one you wish to replace.

In any case, I would not normally recommend this swap no matter which tire is going on because there is more than a 5% difference in overall diameter between the two tire sizes and I don't like to recommend a swap of more than 2% difference in size.

If it is a move that you really want to do, and you are replacing the 205/65's with 195/60's that is the "safest" swap to make because you are putting a smaller tire in place of a larger one and you're not likely to run into a problem with not having enough space for the tire to operate without rubbing. You will experience a noticeable difference in your speedometer reading and may also note some increase in fuel consumption in this case. Expect to spend maybe 5 or 6 percent more on fuel… which can add up over a year to the point that you're really better off to purchase the right size.

Smaller tires to replace 30x9.50R15LT104R tires?

by Kristy
(Suffolk, VA.)

My brother has a 1997 Chevy Blazer that has been lifted and has aftermarket 15" rims and tires with sizes of 30x9.50R15 LT104R.

He needs to get the truck inspected but the alignment is bad and the big tires rub the wheel well (close to the door area). He wants smaller tires and basically wants them to be close as to original (before the truck was "tricked out") as possible with the truck being lifted.

He's wondering to achieve this does he need to buy new rims AND tires or can he fix the rubbing problem with just buying smaller tires? And what would the right tire size be?

tire size for 2003 Mercury Mountaineer

I have an all wheel drive 03 mountaineer. Can I put 275/70R16 size on the vehicle without affecting the all wheel drive? Stock is 245/70R16

Editorial Comment:

The size you are considering, 275/70R16 is considerably wider (30 mm) than your OEM size. This produces a tire which has an overall diameter which is well over 5% larger and this is beyond the limit of 2% that I feel comfortable in recommending for a tire swap which produces equivalent performance. You will experience a speedometer error of nearly 6% but a reduction in fuel costs of about the same amount at a price of having less power delivered to the wheels. Space also might be a problem but this can be determined by making a test fitting.

235/70-16 vs 235/50-18

by pat Gallant
(canada)

Would a 235/70-16 and a 235/50-18 wheel be compatible in the same wheel well?


Editorial Comment:

Your question is a bit too terse to allow me to give you a simple answer with confidence that it would be useful.

I would hope that you have matched the bolt patterns on the two different wheels because if these don't match you're already going to have problems even before you start.

Next it is not clear whether you wish to install an 18 inch wheel or a 16 inch wheel in place of the previous one. If you are going from a 16 inch wheel to the 18 inch one (and the bolt patterns are the same) there should be little difficulty in terms of the wheels. If yu are going from 18 down to 16 it is possible that the vehicle is not designed to use a smaller wheel and you might find that there is a problem with brake clearance. Going to a larger wheel this doesn't present a problem.

There is a considerable size difference in the over all diameter of the two tires you've listed. A much closer match is 235/60 R18 compared to the 235/70 R16.

I would much sooner see you use the 235/60 r18's instead of the 235/50 R18's.

Tire Concerns: is it ok to switch tire size on AWD

by john
(nh)

I am looking for alternative size tires for 2007 Merc Mountaineer AWD with 235/65/18 factory spec tire.

Comment:

The big concern with AWD or 4WD vehicles is that all wheels have the same size tire. In theory there is no problem with switching to different sizes as long as they are the same on all wheels.

Use our Tire Size Calculator to compare the effects of different tires you might want to consider. The best effects are generally found with tires which stay within 2% of the original size. (That is the default setting on the calculator.)

Would 235/50 R17 fit in 2003 Mitsubishi Eclipse

by Renz

I have a 2003 Mitsubishi eclipse and one of my tires got a ripped but is just a small ripped. Now my question is,would a 235/50 R17 profile fit in my car, I want to make it look wide when you look at it at the back so I'm putting this tire profile at the back of my car. Would it still work?

Editorial Comment

There are several versions of the 2003 Mitsubishi Eclipse: The GT's the GS's and the GTS's and each are in a Spyder and plain variety. There is some variation of the tires/wheels which came with these so I don't know what you have since you didn't give enough detail.

Since you mentioned 17 inch wheels, it may be that you may have a GTS that came with 215/50 R17 tires and if that is your OEM size then a 235/50 tire is a close fit but not an ideal size since it is more than 3% larger in over all dimeter and we look to keep the difference within 2% to avoid significant differences in speedometer reading and fuel use.

A better fit would be 235/45 R 17 provided the speed and load rating is equivalent. You could also try a 245/45, but remember that you are using up more space in the wheel well and may have an issue with rubbing when turning when you mount a larger tire.

what size tire can i use?

by jacob holman
(ridgeville, sc)

My car a 2001 ford taurus SES with a vulcan engine calls for 215/60R60, the tires look flat at full pressure in the front..., so i want to use a smaller tire but not sure if its the right thing.

Editorial Comment

The OEM tire size for the 2001 Ford Taurus is 215/60 R16. I assume you made a typo in entering in your information. The manufacturer recommended 30 psi for the tire pressure, but many Tarus users have reported they get a better result with 35 psi all around. Try these pressures and see how it feels for you.

Incidentally, it is normal for tires to look a little bit flat, but not excessively so. If you're not used to looking at them you might mistake a properly inflated tire for being under inflated. I suggest you have an experienced tire technician look at and test your pressure. When you have your tire properly inflated, take a good look at it to get accustomed to how it should look. This is not to say that you should rely on how the tire looks to verify it's pressure, but when it DOESN'T look that way, you definitely know that something is wrong.

I recommend that you carry a tire gague in your glove compartment at all times and use it at least once a month, of not more often.

can 225-60-17 tires for 2005 Chevy Equinox

by Steff
(Richlands, VA)

2005 Chevrolet Equinox

2005 Chevrolet Equinox

original tires are 235-60-17 can 225-60-17 tires be used on a 2005 equinox?

Editorial Comment:

225/60R17 tires are just 6mm smaller than 235/60R17's, which is something you can calculate in your head by simply comparing the two sizes. the 225's are 10 mm narrower than the 235's (235 minus 225 = 10). Multiply that by the Aspect Ratio of 60, so 60% of 10 = 6.

A 6mm difference in sidewall height, especially being smaller is hardly likely to cause much of a problem from any point of view.

Changing the tire size on a Dodge 2002 Minivan

by Robert
(Murray, KY USA)

Can I change the tire size on a 2002 Dodge Mini-van from the recommended 215/70R15 to a 215/65R15 without causing any problems or using more gasoline? Also, does Kumho make a reliable, safe and good product?

Editorial Comment:

The 215/65 r15 tire is smaller than the 215/70 R15 you currently use. This means you will use more gasoline because, being a smaller tire the vehicle will travel slightly less distance each time the wheel rotates. This will also affect the speedometer reading.

Kumho is one of the major tire manufacturers in the world today and is highly respected and regarded by many users.

Tire Concerns: Larger tires

by Andrew
(Oswego, NY, USA)

What concerns are there with my used, unmodified, 1996 Geo Tracker with larger 235/75R15 tires than the OEM size 205/75R15 tires?

Editorial Comment:

Basically you wish to install a wider tire on your Geo Tracker. Automatically when you change the width, and the other dimensions stay the same, the height of the tire increases too.

To learn exactly what the differences are, compare these two tires using the Tire Size Calculator.

In general terms, however, a wider and taller tire means that your speedometer will show that you are travelling at a slower speed than you really are, and you will be using less fuel along with having less power reaching your wheels.

Because the tire is both wider and taller, you may find an issue with space, either in turning or when the vehicle is loaded and passes over a bump in the road causing it to rub against some part of the vehicle.

I don't think it is an issue in your case, but another issue which can arise is that your rims could be too narrow for the wider tire since each tire is designed to be used on a certain width of rim. An experienced tire technician should be able to tell you if the rims you now have will fit the new tires you want to use.

225/75/r15 on 2007 Merc. Mountaineer

Can I put all 4 new rims and tires, size 225/75/r15 on my 2007 mercury mountaineer?


Editorial Comment:

All the data that I have available about the 2007 Mercury Mountaineer shows wheels available from 17 inches up to 22 inches in diameter.

The bolt pattern, which is essential for any wheel is 5-114 and this will not vary no matter what rim diameter you use.

The problem with going down to a 15 inch wheel, even if you find a wheel with the corresponding bolt pattern is that you may not have enough space inside the wheel for the braking assembly.

In addition you will need to increase the aspect ratio of your tire in order to maintain an outside tire diameter which is somewhat similar to the original equipment. The narrower the tire/wheel the more you need to increase the a/r to compensate.

The 225/75 R15 you mention is actually more than 4% smaller than the original size of 245/65 R17 offered in one of the original purchase options. I never recommend that anyone select an alternate tire which is more than 2% different (bigger or smaller doesn't matter) than the original … it just causes too many headaches.

If you can test fit a 15 inch wheel and find that it fits without causing any conflict, then your best choice of tire size would be 255/70 R15 or 265/70 R15

Replace 225-60 r16 with 205-65-r16

Is it possible to replace 225-60 r16 4 season tires with 205-65-r16 winter tires on a '98 lincoln continental

I need to install winter tires, and have come across (4) 205-65-r16 winter tires. Will they fit on my 16" rims?


Editorial Comment:

You are on the right track when thinking about changing tire size. If one of the numbers in the size increases, the other number should decrease to compensate. When you follow this principle you then only need to check the exact measurements to see if the swap is a good one.

In your case, switching from a 225/60 to a 205/65 is a remarkably close match. The overall diameter of the winter tire you are contemplating is barely 1/2 of 1% different from the original, and this … in terms of performance and fuel consumption is a good match in my experience.

You need to make sure that the new tire has the load-carrying capacity for your heavy car and if it does, then go for it!

Editorial Comment:

This is a clear case of a place where you could have saved yourself considerable time by using our Tire Size Calculator.

Comparing the size of your two different tires in the calculator you would see that there is only a 0.38% difference (almost nothing) between the two tires.

Possibly if you had looked up the tires available for sale at TireRack you would have found both sizes listed as alternatives which were offered for that vehicle. It is evident that somewhere in the life of the vehicle a previous owner switched wheels from what originally came on it, but the swap was done within acceptable parameters.

I have just had a puncture in my near side rear tyre. These tyres were upgraded to R17 from the original R16. Trouble is I still have yet to buy a spare for the R17. To drive to the tyre technician's to repair the puncture, can I put one of my R16 as emergency spare for the 15 min. journey?

It is difficult to give you a reliable reply because you have not provided some details which would make the issue much clearer. For example, what was the original R16 tire size and what is the new R17 tire size? What is the size of your spare tire? Perhaps the make, model and year of your vehicle might make a difference, too.

If your "upgrade" as you call it was what is called plus-sizing, this means the the over all diameter of your new tires are the same as the older ones. This may also mean that the spare tire, especially if it is a compact spare, and it was suitable for the R16 tires, will also serve for the R17's but only as a spare.

You are safer with an odd sized tire on the rear because it will not be as difficult to control your vehicle and if you are driving slowly for a short distance you can probably make it to the repair shop.

If you vehicle is a 4WD it is not recommended driving for any distance with unmatched tires in any position, but for a short drive at a slow speed and with ample caution you are not likely to cause any major damage or have any safety issues.

can i use 235/70/16 tires on a 2006 trailblazer?

by Cathy Swain
(Lexington Ky)

I have 4- 235/70/16 tires and they are great tires but my trailblazer has 245/75/16 on it and i dont want to mess anything up.

Editorial Comment:

The 235/70/R16 tires are considerably smaller than the 245/75's that your Trailblazer now has. The over all diameter is more than 1 1/2 inches smaller which represents a change of nearly 5% in size. This is way beyond a 2% difference which I usually recommend as a limit when changing tire sizes.

Since you already have these tires, I'd recommend you try to swap with someone if you can maybe for 255/70 or 265/70's which would both be a better fit. Or simply see if you can sell these tires to somebody who needs that size.

Went from 15" to 16"

by Darrell
(Baker, LA)

Chevrolet Malibu

Chevrolet Malibu

I drive a 2001 Chevy Malibu. I originally had 205 65r15's on my car but my dad bought 225 60r16's from an impala to put on the car. I put them on but am worried if it would be a huge problem to the car to drive around with those bigger wheels on the car especially with no special modifications for them

Editorial Comment:

Your tire swap has worked because the difference between the two tires isn't really as much as you might think at first. Even though you might not of been aware of it you have an example of the principle which is used when Up-Sizing is practiced … that is you will compensate for a larger tire diameter by reducing the Aspect Ratio, which is the second number in the tire's size.

The Aspect ratio is a percentage which is applied to the first number in the tires size (the width) to calculate the height of the sidewall. If you make a tire wider but reduce the AR, you can end up with a tire which is the same over all diameter.

In your case the 16" tire is still a bit more that 4% larger than the original so you will be seeing you speedometer reading about 4% slower than your real speed. The positive benefit is that you'll be using less fuel.

If you're interested in finding a tire which is more closely matched in over all size to your original, the best 16" tires would be either a 205/60 which is the same width or 225/55 for a wider tire like the one you now have.

Tire Concerns mixing 215/60R16's with 215/65R16 tires

by Daniel
(Barbourville,Kentucky, USA)

I recently bought a used car with new 215/60R16's on the front. The back tires are both plugged. I have some barely used 215/65R16's. Would it be a big difference to mount them on the back?

I bought an Oldsmobile alero that has 225/60's on back and 215/60's on front.The 215/65's came off a Mercury cougar and I know they are gonna be a higher profile.Im just wondering how much and if its safe to do.According to my math they will be around 1/2 inch bigger/Higher. Safety is my main concern but I cant afford to buy 2 new tires especially if I dont have to.

Editorial Comment:
Wikipedia tells us that the Alero was introduced in spring 1998 as a 1999 model to replace the Achieva and Cutlass. It went into production on April 6, 1998. and they were all built in Lansing, Michigan. The Alero was Oldsmobile's last compact car as well as the last vehicle sold under the brand. The last one was made on April 29, 2004.

It seems that the OEM tires on your car might have been 215/60's all around, but an alternate size was 225/50. The 225/60's on the back are taller than the ones on the front and if the 215/65's are even higher you are complicating the situation even more.

I suggest you go back to basics and start by comparing the 215/60's to either the 215/65 or 225/60 that you wish to use and compare the effects using our Tire Size Calculator.

The extra size might produce some problems in the space that is available for them to run in, but if that proves to be OK and you are prepared to accept the other consequences, my suggestion is that you aim at getting all 4 tires the same size, otherwise you will always have a potential problem with which size to carry as a spare tire, and the rotation of your tires to even out the wear, because no one tire will wear in the same way as another on a different position so you will get longer tire life by doing a periodic rotation and carefully inspecting the wear to determine if there are signs of any mechanical problems coming up.

205/55r16 on front & 205/60r16 on rear

Would it be mechanically harmful to my car if I run a set of 205/55r/16 tires on front and 205/60r/16 tires on rear. My car is front wheel drive. Your expertise is much appreciated...

Editorial Comment:

From a purely mechanical point of view there is no problem in running with different sized tires on different axle as long as the vehicle is not a 4 wheel drive. If you have a 4X4 most manufacturers will caution about mixing tire sizes because this could cause serious mechanical damage.

From a more practical point of view consider what you are going to do in terms of a spare tire. Are you going to carry two spares? Are you going to call a towing service if you get a flat? It is not advisable to drive with different sized tires on the same axle because of performance and handling issues. Yes you might try to minimize the difference by reducing the air pressure on the larger tire, but even if this works you may ruin that tire by running it with lower pressure, so you then have two bad tires instead of one.

Unless your vehicle has been specifically designed to use different sized tires on front and rear axles, I suggest you're better off sticking with the same size all around.

225/55r16 for 1998 toyota Camry

by andre
(Englewood, nj)

Currently I have 225/50r16 however I would like to get 225/55r16 for more thickness. This way it will fit up the wheel well better and a softer ride because of thickness.

Editorial Comment:
I don't have the exact dimensions of the 1998 Toyota Camry, but I can tell you that, in addition to being wider, the 225/55R16 tire is also slightly higher than the 225/50R16.

This is easy to notice because the 50 and 55 are the aspect ratios used to determine a tire's sidewall height from the tire's width. 50 means 50%, 55 means 55%. So it is obvious that 55% is 5% more than 50 and the tire height will increase by 22.5 mm.

Why 22.5 instead of 11.25, you ask. Simple, when you look at your tire you have two sidewalls to measure if you are calculating the total diameter of the tire. If you look at it vertically you have the sidewall on the top of the tire, next you have the wheel, and at the bottom you have the other side wall. Each side wall has increased in height by 11.25 mm which, in total is an extra 22.5 mm which has to fit into your vehicle's wheel well.

Do you have enough space to accomodate and extra 22.5mm (that's just under one inch)? Some vehicles have plenty of room to spare, others are very tightly spaced. The best way to be absolutely sure is to do a test fitting by putting an inflated, mounted tire of the size you are interested in using and seeing how it fits.

Toyota Camry Correct tire size

by Garry Woods
(Winnipeg, Manitoba, Canada)

2001 Toyota Camry LE

2001 Toyota Camry LE

Can I safely use 215 60R 16 tires on a 2001 Camry whose book size says to use 205 60R 16 ?

Editorial comment:

I suspect that there will be little difficulty posed by using a 215/60 R16 tire instead of a 205/60 on you Camry because the difference in sidewall height is just 6mm and the overall diameter change will be less than 1/2 an inch (12mm). You can see this by comparing the difference in widths which is 10mm and multiplying that by the aspect ration (60%0 to give you 6mm.

Check out our Tire Size Calculator to see the other consequences.

p265/60/18 tires for 2004 navigator

by victor
(houston tx)

i would like to install p265/60/18 michellin tires on my 2004 navigator, right now it has p255/70/18 tires

Editorial Comment

The OEM size tire for the 2004 Lincoln Navigator 2WD is 255/70R18.

If you use our Tire Size Calculator to compare the 265/60/R18 tire with this size you will see that it is not the best choice because it is more than 4% smaller in size. In my opinion a 265/65R18, if you can find it available would provide a much better match.

If not even the 265/70R18 is a closer match. Both of these are less than 2% different in over all diameter from the original.

225/70/r15 vs 225/70/r15

by Kayla
(Missouri)

Oldsmobile Silhouette

Oldsmobile Silhouette

I want to replace my 215/70/r15 tires on my 2000 oldsmobile silhouette van with 4 new 225/70/r15 tires. Would that work? Or would that be dangerous?

Editorial Comment

Normally a change in tire size, especially just one size (lie 215 to 225) isn't something that we consider dangerous but it may not be a change that we recommend for other reasons.

What you need to realize is that increasing the width of a tire, also increases its height because the second number (the Aspect Ratio) is a percentage, so if the first number increases and the second one remains the same, then the result of multiplying the two together will be bigger.

When you increase the size of a tire in width, you need to be mostly concerned with what happens when you are turning the steering wheel to the extreme left or right, in addition to the extra space occupied by the tire on the sides.

When a tire's diameter, or sidewall height increases, there is also a space issue, but this will affect your vehicle's performance: its speedometer will not be accurate and you will experience a difference in fuel consumption because each revolution of the tire will move the vehicle a different distance than the other tire.

When the changes in a tire's size is small these differences are also small and, as a general rule I consider a change of up to 2% small enough that it isn't really worth worrying about, but when you go past that arbitrary limit, you want to be more cautious.

In the case you present, going from 215/70R15 to 225/70R15 the difference is just a fraction over my arbitrary 2% limit so as long as there isn't a space problem I wouldn't discourage you from doing this.

Can you put a 215/70/15 tires on 2003 Mitsubishi Eclipse

by Mike
(Calgary)

I have a 2003 mitsubishi eclipse that needs tires. Since it's winter time already I'm thinking of buying a second hand winter tires to beat winter and I'am wondering if I go for small tire size, would it make any difference or problems?

Editorial Comments;

I'd suggest you look at our Tire Size Calculator before choosing any alternative tire to get an idea of what you're facing.

These comments apply to any vehicle, not just the 2003 Mitsubishi Eclipse.

By smaller, I'm interpreting that to mean smaller total diameter, but sticking with the same wheel diameter as you already have. If you go to a small sized rim, you are opening up an entirely different kettle of fish and one which I wouldn't encourage you to do unless you are very adventurous and willing to experiment.

If there is less than 1 inch total difference in the inflated tire sizes the only big concern in terms of suitability is that you might have problems with ground clearance if you drive in areas where you might have a possibility to bottom out (i.e.. scrape the ground). In the winter the lower the tire the sooner you will be pushing snow if you are driving in unploughed roads.

With a smaller tire your speedometer will show a higher reading that your actual speed and you will be using more fuel per mile/kilometer because the wheel will have to revolve a greater number of times to cover the same distance as the larger, original tire.

Also, when choosing a smaller tire, you need to pay attention to the speed rating and load rating of the tire to make sure you are using one which is not less than the OEM tire.

Tire Concerns: Smaller Winter Tires

by Ron
(Ottawa)

I would like to know if I can mount 215/65r/16 winter tires (already on rims) on my vehicle
which has 235/65r/16 all seasons at the moment. Is down sizing by 2 sizes too much?


Editorial Comment:

This type of down-sizing isn't of great concern except for the possible inconvenience of having a slightly lower ground clearance. You are decreasing the width by 20mm so you are losing 65% of that in height, or some 13mm -- which is about 1/2 inch. If you can live with this amount of reduced clearance then this shouldn't present any problem.

Often, there's much more reason to be concerned if you're going in the other direction because you may not have sufficient space when increasing the tire size, but a downsizing seldom is something that brings disastrous consequences.

205/70R15 Tires on a 2001 Oldsmobile Alero

by Erick
(S.B, Indiana)

Original Equipment Tires from Oldsmobile made for this car are P215/60-R15, (Current tires on Alero: 205/65-R15).

Would 205/70 R-15 fit on this car and this car's original steel 15" rims?

The tires I am getting are coming off a 1997 Chevrolet S10, (The S10's original size tires when manufactured are 205/75-R15); the tires currently on the s10 are not original manufacture tires: for some reason they put 4 tires of 205/70-R15 which increases revolutions and decreases real time speed, vs Speedometer.....

I used the discount tire store tire calculator and it said the following, Mounted mind you:


Tire 1(205/65-R15) Tire 2 (205/70R15)
Sidewall Height: 5.08 5.65

Section Width: 8.46 8.07

Overall Diameter: 25.16 26.3

Circumference: 79.03 82.62

Would the Wall Height of 70 be ok? or would I be risking Rubbing/impact on the Wheelwell walls? Mainly concerned with the front as the front has more weight considering the engine, Transmission case, the rear of the vehicle I am not too worried about.

Editorial Comment:

I have one problem with your comparisons: You are comparing the proposed tire with the actual tire and not the original tire which the vehicle was designed to use. So, you are starting off with a tire which is already LARGER than the OEM and now want to go even bigger.

The first increase wasn't a bad match ... it was only about 1% bigger than OEM but the one you are thinking of is almost 5% bigger in over all size. This far exceeds the 2% limit that most professionals recommend for a swap.

The problem with possible rubbing is something that you need to discover using a test fitting with the tire inflated to the pressure which you intend to operate the vehicle. Because of subtle changes that can occur because of mechanical work and wear in the suspension and steering of the vehicle you should not rely on advice from others whose vehicles might not be in the same condition, especially if you are looking at an area where the space may be very limited.

215 65R17 tires vs 235 65R17 on the rear

by Lucas
(Bloomington )

2010 Challenger

2010 Challenger

I have 215 65R17 tires on my 2010 Challenger SE, I want to put 235 65R17 on the rear but I'm told the suspension wasn't built staggered only the v8 were.

If I go with a 235 60R17 in the rear, will it give the car an old "muscle car" look, or am I wasting my money

Editorial Comment:

I'm not really clear on what you expect to achieve from this change, especially since you talk about 235/65 and 235/60 tires, so it's not clear which ones you mean.

In either case, however, there is not a tremendous difference in the radius of either sized when compared to the 215/65's which you say are currently on the vehicle. With the 235/65's the difference is only about 1/2 an inch and in the case of the 235/60's is about as thick as a fingernail. Is this likely to produce the effect you are looking for?

Because of the small difference you're not likely to have any major problems with fitment, but the larger of the tires is still beyond the 2% limit which I normally like to use as a limit for tire swaps. You will experience a difference in speedometer reading and fuel consumption of over 3% in the 235/65 tires, and virtually nothing if you use 235/60's.

Tires for 2000 Pontiac Montana.

by Sarah
(Bc)

2000 Pontiac Montana

2000 Pontiac Montana

Currently my van has 215 70r15. I want to buy some winter tires that are 215 70r14 will this work?

Editorial Comment:

I truly hope that you realize that if you get 215/70 R14 tires for your Pontiac Montana, that you are going to have to purchase new wheels, too.

Under absolutely no conditions should you ever try to mount a 14 inch tire on a 15 inch wheel! (or the other way 'round).

If you do get a new set of wheels and choose this size of tire you will end up with a smaller overall size which is beyond the size difference which I like to recommend.

If you definitely want to get a set of 14 in wheels, the sizes I would rather see you use would be either 215/74 r14 or 205/80 r14. Both of these sizes stay within the 2% limit which I recommend for changing tire sizes.

225/55/R16 vs 235/70/16

by dave
(vermont)

2006 Honda Pilot

2006 Honda Pilot

Can I substitute 225/55/R16 for a 2006 Honda Pilot with 235/70/16?
Can I make this change without dramatically affecting performance?

Editorial comment:
My first impression is to say that this is an undesirable swap. Why? Because the first two numbers in the proposed tire size are BOTH bigger. The very first thing I look at before doing any calculations is to see if one number is bigger, the other number should be smaller. Next I do the calculations.

Now the calculations prove out my suspicion that the difference in size is more than the 2% limit which I usually consider acceptable for a swap to be made without resulting in any significant performance issues.

In your case the 235/70 tires are a whopping 12.46% bigger than the original tires you mentioned. This will end up with your car speed being that % MORE than what your speedometer shows, your power reaching the wheels will be over 12% less, however your fuel consumption would also be reduced by that amount.

Since the car is designed to operate with a certain amount of power, you'd likely consider the car to seem sluggish.

Another issue is the space in which the tires will operate. It is possible when you go beyond certain limits that you will have a tire rub against or hit another area of the chassis, perhaps only on bumps or when turning depending on the actual design of the vehicle and the size of the tires. This can often be determined by doing a test fitting of the proposed size, but you should never make a large size change without at least doing a test fitting unless you have had the benefit of someone else having tried it with good results.

Tire Conderns: 265/75R15 tires for 1990 ford f-150 stock rims

I have a 1990 ford f-150 with the stock rims on it. I want to put a pair of 265/75r15's on the back on the f-150 stock rims. Is this possible and will the tires fit?

Editorial Comment

The 1990 Ford F-150 came with two optional tire sizes as OEM, 215/75 and 235/75, both 15 inch diameter. A 265/75 tire is too wide for the stock wheels which may have been supplied to fit the 215/75 tires

If the wheels you have are for 235/75-15 tires you may get away with using the 265/75 tires on them provided that the flange width is at least 7 inches. If the width is not this wide then you may have wheels which were supplied for the 215/75 tires and those are not allowed to be used for 265/75 tires.

Tire size

Will p225/55r16 tires fit on a 2009 Pontiac vibe?

Editorial Comment:

When I receive a question like this I am led to wonder if people who ask questions on the internet think that the people who respond somehow have a way to know every possible detail about their personal situation.

If you would have asked your question by giving more information, such as what size of tire your car came with, it would save me time having to look up that information and make it easier to answer.

In your case, I have found that the 2009 Pontiac Vibe came with at least two different tire sizes 205/55-16 and 215/45-17 and perhaps more because there are several different variation of the Vibe model. So, by not providing this information, I may be giving you information which is totally useless in your case unless I spend 15 or 20 minutes researching all the details that are missing.

If your vehicle came with 205/55r16 tires then without even consulting our Tire Size Calculator (which you can find in a link below), that this is not a swap I would like to recommend because you are increasing the width by 3 steps from 205 to 225 without making any adjustment in the Aspect ratio of 55. This means the tire will be not only wider, but also higher.

The over all difference in tire diameter will be about 3.48% in this specific case and that is almost double the limit of 2% which most tire people try to stay within in a normal tire swap. A much better size for this would be a 225/50r16 which is almost exactly the same diameter but with the same width.

I am no personally familiar with the Pontiac Vibe so I don't know if there is enough space in the wheel wells to utilize a tire of this width. Usually the best thing to do is try a test fitting in the most restricted part of the car and try turning your steering to the extreme left and right sides to make certain there will be no rubbing.

Apart from that take care that any tire which you substitute for an OEM tire has at least the same or greater speed and load ratings so that you don't install a tire which will fail because it can't handle what you need it to.

235/55R18 for a 97 Ford Explorer

by Ken
(Beloit WI.)

I found some tires and Rims I want to use on my truck...
Will 235/55R18 on 5 lug Dodge rims, will they fit on a 97 Ford Explorer 245/75R16 with 5 lug rims. I guess I would like to know if dodge and ford rims are still interchangeable.

Editorial Comment:

You haven't provided enough information to allow me to give you a good answer to your question.

There are many different rim sizes that different Dodge models have so before stating that Dodge and Ford rims are, or are not, interchangeable I'd need to know exactly what year and model the wheels are from.

For example the 2000 Dodge Ram has a Bolt Pattern of 5-139 while the 97 Ford Explorer has a Bolt Pattern of 5-114. Even though they are both 5 lug wheels, the spacing between the bolts is different, so in the case of these two vehicles, the wheels are not interchangeable. Just being 5 bolts isn't enough.

Apart for the wheels fitting, you also have to determine if the vehicle construction will allow the wheel to fit. Of course when the replacement wheels are larger in diameter you may not have any problem with the wheels, but if they were smaller there might be some interference with brakes which fit inside the wheel.

After you are sure that the bolt pattern and wheel size with work you then need to consider the overall size of the mounted tires. You can use the Tire Size Calculator on this site to compare two different tires to see how they measure up. If there is more than a 2% difference I don't usually recommend a swap, but within that limit there is a good chance that the swap will work.

Tire Size on my 2003 Ranger 2wd xl

by Dave
(anytown , ohio USA)

sticker on ranger

sticker on ranger

sticker on ranger
new tire

I just had new tires installed on my 2003 ford ranger 2wd xl. On the door sticker it says P225/70R 15SL. The tires they installed are Firestone Destination LE 2 SL size is P215/75R 15SL. What will these smaller tires mean in proportion to handling, tire life, safety. The original tires were Goodyear Wranglers size P225/70R 15SL and they were worn out. The dealer which is reputable btw said these firestones were a comparable fit. The new tires look small which I know they are and I'm planning a 1600 mile trip next summer and safety is a concern. I don't haul or pull anything of significant weight maybe upto 500lbs max but rarely.

Editorial Comment:

It may surprise you to learn that the 215/75 tires are just a wee bit larger, in total diameter than the original 225/70's. This is because the AR was increased from 70 to 75. This number is multiplied (as a percentage) to calculate the sidewall height.

It is a usual practice in substituting different sizes to increase one number in the size when another number decreases. This will compensate for the change and maintain the final overall diameter the same, if the proportional changes are the required amount.

In your case the 215's are 10mm narrower which is less than 1/2 inch but the overall diameter is almost 1/3 of an inch larger making is just over 1% bigger. This is an excellent substitution in my opinion and I would not argue over it, especially if you find the price and availability of this size more convenient than the original.

tire size question for Cheverolet Venture

by Chad
(Cornwall Ontario)

I have a 2001 Chevy venture van and the placket on the door say the tire size should be 215/70R and I replaced them with winter tires that are 215/60r I was just wondering if this is going to change the speedometer in my van any help on this topic would be great...?


Editorial Comment

You didn't specify the wheel size in the door sticker so I had to spend some time to look up the OEM size to confirm that the 2001 Cheverolet Venture used 215/70R15 tires. If this matches with what you have, then my comment will be valid, otherwise it may not be pertinent.

A 215/60 tire for that wheel is considerably smaller than the oem size... the exact difference is 6.3% less which puts is far beyond the maximum difference of 2% that I recommend for a tire swap. You can expect that this tire would produce an error in you speedometer of 6.3% and you will also use that same percentage of extra fuel. Depending on how long you have those tires in use that extra cost in fuel could add up to more than the difference in price in getting a correctly sized tire.

Alternate tire size for 2005 Astro Van

by J Hollander
(Los Angeles, CA)

For a 2005 Astro passenger van.

Standard tire size is P215/70 R16.

Will size P265/65 R16 work ok. It is supposed to have the same diameter and fit factory wheels.

What concerns should I have by using this size over the factory standard size used on the 2003 through 2005 Astros?

Editorial Comment:

You are correct that both the P215/70 R16 and the P265/65 R16 tires are designed for a 16 inch rim but there's more to it than just the diameter.

Think of the 16 in a tire size like a shoe size. Some people have narrow feet and other's have wide feet. The same thing with tires. A 265 tire is definitely "fatter" than a 215. The difference is 50mm, or very close to 2 inches wider. Just like a person who needs a wide shoe is going to be extremely uncomfortable if they have a narrow size, this tire too is not likely to fit.

I don't have the exact numbers at my fingertips for these two tire sizes, but all tires are designed to be used on rims of a certain width. Often there is a bit of flexibility allowed so that a person can go a bit wider or narrower, but most of the ranges in tolerance I've seen are about 1 or possibly 1 1/2 inches so even if your rims, which were carrying the 215 tires were at the widest possible width, it is a very slim chance that that would be wide enough to be acceptable at the lower range of the widths that a 265 tire could use.

It's not just "comfort" we're talking about when it comes to tire widths and rim widths. A tire which is placed on a rim which is too narrow will not seal properly and possibly could come off in use if you do manage to get it to inflate at all.

The 265 tire is also going to be higher than the 215 even though the aspect ratio was lowered. The difference is more than 6% of the original and this is beyond the range that I consider advisable for an equivalent swap. In theory this tire would produce a speedometer error and a reduction in fuel consumption of about 6%.

My advice would be to avoid this choice.

245 70 17 t on 2003 gmc envoy xl

have 255 65 17 right now just wondering if 245/70R17 tires will rub the control arm.The stock size is 245 65 17.

Editorial Comment.

The 255/65R17's which you are now using are already larger than 245/65R17's which you say are OEM for your vehicle. Now, a 245/70R17 is only a bit more than 1% larger but if you are already running close to not having enough room, there is a chance they these might cause rubbing.

Your best bet is to try a test fitting before you make a commitment to buying this size to make sure that there is enough clearance. Especially if there is a minimal amount of clearance to begin with you might want to be very careful about this because even a small change in clearances because of a mechanical change (example hitting a pot hole) could remove the advantage you had.

tire size for honda civic

by winnie ross
(tillsonburg canada)

can i put 215/60r16 on a honda civic ale car which has 205/55r16 tires.

Editorial Comment:

The general rule to look at whenever you are considering changing tire sizes is to look at the first two numbers in the sizes. If one of the numbers increases, then the other number should decrease. If that does not happen, you should suspect that the change isn't a good idea.

In your case going from a 205/55 to a 215/60 tire both numbers are increasing meaning that even without doing any calculations we know that the new tire is bigger.

The difference in this case is over 5%. Your speedometer will show 5% lower speed than you are really traveling. You will also use 5% less fuel but will have that same amount less power reaching the wheels.

Since this is greatly more than the 2% difference I normally recommend I don't recommend this swap.

P235/75R16 for 2002 Buick Rendezvous

2002 Buick Rendezvous

2002 Buick Rendezvous

I have a 2002 Buick Rendezvous can I put these tires on them P235/75R16?

Editoria Comment:

The 2002 Buick Rendezvous has a standard tire size of 215/70 R16 and you wish to install 235/75 R16.

This is a tire which is both wider and higher than the original size and when all is taken into account you would end up with a tire which is more than 7% larger. This is not recommended and is not a good choice.

If you want a wider tire you might consider a 235/65 R16 (remember when you increase the width you need to decrease the aspect ratio). If you want a higher tire consider a 195/80 R16. Both of these tires preserve almost the same overall tire diameter and will not affect speedometer or fuel consumption very drastically.

225/60/17 tires for camry

Toyota Camry

Toyota Camry

I have a Camry with 215/55/17 street tires. I have ben offered 225/60/17 snow tires. Will there be a problem with the wider 225 tire fitting.

Editorial Comment

According to my specifications the 215/55/17 tire is the OEM tire for the 2009 Camry SE. If your vehicle is different from that, the original size may vary.

You are thinking about using a 225/60 r17 tire, and right from the start I feel uncomfortable because the basic rule of substituting one tire size for another is if one of the numbers increases, the other number should decrease to compensate. In this case both of the first two numbers is increasing so I know that this tire is definitely going to be bigger.

Doing some calculations we see that the overall size of the 225 tire is more than 5% bigger than the original, and this is not generally a good idea. My maximum size difference, except for very special cases is 2%. You will expect to see a noticeable error in speedometer reading and a decrease in fuel usage if the tire will fit to operate in the limited space available in the wheel well.

I do not recommend this swap but if you do wish to try it, make absolutely certain you try a test fitting, and checking that there is sufficient space to allow it to operate without any conflicts.

Pros and cons to tire size differance

by Mark Brown
(Albany,Oregon)

2001 Chevy Cavalier

2001 Chevy Cavalier

2001 Chevy Cavelier requires P195/65/R15 all around.
Will P195/60R14 mess anything up?
Can I run these with confidence?


Editorial Comment:

To use your terminology, yes, this will mess things up … possibly more than you think.

First you will need new wheels, because R14 tires cannot be used on a 15 inch rim. Next, it is possible that 14 inch wheels will not work on your vehicle. Then, even if you can get 14 inch rims to work on the car, the difference in overall size of the 195/60 r14 tires is well over 7% compared with the 15's. I seldom recommend a size difference of more than 2% when swapping tires, so this is far too much to make me feel comfortable.

will185/60/r15 tires fit on a 92 astro van

1992 Astro Van

1992 Astro Van

I found some tires on line and mt tires are 225/70/ r15 and ineed to know if the ones I found on line which are 185 /60/r15 will fit ?

Editorial Comment

Why you would even consider a tire which is so different from your original is hard to understand. Are they offering to pay you to take them?

To begin with there is so much difference in the tire width that it is likely that you will have to buy new wheels for the 185/60's to fit. Next, when you get them to fit on your wheels, you will be using a tire which is over 13% smaller than your present tires which means that your fuel consumption will increase by at least 13% and you will be going much slower than what your speedometer reads. Like around 87 mph when the speedometer show 100!.

A very bad choice all round from my point of view!

replacing 225/50R17 tires with 225/55R17 tires

by Moe
(Canada)

i traded in my Buick allure using 225/55R17 snow tires which i kept, my new 2012 Ford fusion is using 225/50R17 tires. Can i use these snow tires on my ford in winter time. They are mounted on rims.

Editorial comment:

Below are the wheel specs on some replacement wheels that are offered for both the vehicles you have mentioned. Note that the Buick Allure is the Canadian version of the Buick Lacrosse which, I understand are identical except in model name.

Note that the bolt pattern is slightly different in the two vehicles. Some people feel that with such a small difference in bolt spacing of just 1mm you can switch wheels without any problem.

You may have to file the bolt holes slightly to have a better fit, and this is something that makes me a bit uncomfortable. Clearly you're not making a major change, and the precise fitting of the wheel studs isn't as important as many other things and other people have done this without any serious consequences.

ford
Offset: 45mm
Backspacing: 5.98"
Bolt Pattern: 5-114
Rec. Tire Size:225/50-17

Buick Lacrosse
Offset: 42mm
Backspacing: 5.62"
Bolt Pattern: 5-115
Rec. Tire Size:225/55-17

The Buick's tires are larger in diameter than the ford's and this will cause some distortion in the speedometer reading of over 3% which is beyond the range that I normally consider acceptable for most people, so in the end, I would not recommend this swap but, at the same time I don't see it as something that will create a major problem if you decide to do it.

tire sizing

by Casey
(Ukiah, CA)

I've got a 2003 Honda Pilot. I'm looking for a heavier duty tire as I pull a trailer and haul some pretty good loads. My local tire guy says that in my size (235/70/16) there are no such thing. I'd like to move up to a 75 series tire where I can get a light truck tire. Question: will a 75 series still fit and function on my car?

Editorial Comment:

I believe you won't have any problem finding a 75 series tire that will fit in your vehicle and allow you to use the same wheels, too.

To make sure you have the minimal effect on performance, you'll want to go to a slightly narrower tire to compensate for the higher aspect ratio. 225/75 R16 seems to be a good possibility which seems to have a wide variety of tires that would allow you to get a higher load rating.

You might also look at the 215/75 R16 as another alternative. Both these sizes are within a 2% size difference which meets my criteria for swapping tires.

245/60-R18 tires for 2010 Toyota RAV4 Sport V6

Will replacing my original tires 235/55-R18 with 245/60-R18 bring any mechanical complications on a 2010 Toyota RAV4 Sport V6?


Editorial Comment:

This swap is not one which I would normally recommend because the 245/60 tire is almost 5% bigger than the 235/55.

This will result in a 5% speedometer error, less power to the wheels and a similar reduction in fuel consumption.

You will also have less space in your wheel well which needs to be carefully considered and tested with a trial installation to make sure you do not have any issues with rubbing either on rough roads or when making extreme turns to either side.

185/65 R15 on 2003 Camry

2003 Camry LE

2003 Camry LE

The manufacturer specs for my 2003 Camry are 205/60R15. Will 185/65R15 do well on the vehicle? The tire calculator indicated that the differences are minimal, is that correct? What will be the difference in driving? Thanks in advance.

Editorial Comment:

You are absolutely correct, the difference between the recommended 205/60R15 and the 185/65R15 tires which you are considering are minimal … almost so little as to not make any difference in performance at all.

However, just size is enough to consider, if every other specification of the tires are the same. By that I mean things like speed rating and load rating. Also there are some people who claim that a narrower tire will reduce the size of the contact patch, but this is not entirely true. The area which touches the ground will be narrower, but with a slimmer tire the patch will likely be longer unless you were to increase the tire pressure.

You might, however, be disturbed to learn that this tire will likely cause a slight increase --about 0.88%--in fuel consumption. It isn't a great amount, but you should be aware of this possibility.

Tire Concerns: Higher aspect replacement tires?

by Ybrevic
(Wisconsin)

I have a 2010 Elantra Touring SE on which the original Kumho Solus KH16 tires are to the tread indicator at under 30k miles. Favoring greater traction and increased treadwear over race car handing, would it be possible/advisable to put a higher aspect/wider tire (e.g. 215 or 225/50 or higher?) on the existing 17 inch wheels?

Editorial Comment:

It may not be necessary to change your tire width or aspect ratio if you're simply interested in getting improved tire life.

To start you might want to read the article I've written on tread wear.

It seems that you may have a tire which has a rubber compound which gives it better handling and grip but has the disadvantage of wearing out faster than other tires. These are often called "High Performance" tires.

Tell your dealer that you don't want high performance tires but prefer longer life (look for a higher tread wear rating on your tire).

Chances are that you will be able to do this without changing tire size, and if you can, you may be better off because then you avoid other issues that arise.

If you definitely need to consider another sized tire, use the Tire Size Calculator to find a tire which is very close to your original.

Can I put 215 60r17 tires on my 2006 town and country?

by Lindsay
(Colorado)

The tires I'm looking at are used. They have less than 3000 miles on them and came off a jeep compass. They are sumitomo touring LST tires and I know the person selling them and trust them. I don't know much about tires but I know that if these tires fit my van they are a pretty good buy. Does anyone know if they will fit? Thanks for your help!!

Editorial Comment:

The first thing you need to do whenever you wonder if the tires from another vehicle will fit on your vehicle is look on your vehicle an see what size tires it has. If there's an exact match you're almost home free as long as the speed rating and load rating of the tires are the same or greater on the alternate tires.

According to my information, the 2006 Chrysler Town and Country came with 15 or 16 inch wheels as OEM. Since the tires you are considering are 17 inch, it would seem that they would not fit unless you are using 17 inch rims. If your rims are not 17 inch you'd have to get the appropriate rims, in addition to the tires and in the end you may end up spending more than you would if you just went out and bought new tires that fit your vehicle.

If you think about swapping the rims from the Jeep this will only work if the bolt pattern and spacing on your vehicle matches that of the Jeep.

235/55r18 vs 235/50/r18

2008 Chevy Equinox

2008 Chevy Equinox

Can i use 235/55 r18 inplace of 235/50 r18 on a 2008 Equinox Sport?

Is there going to be enough wheel clearance?


Editorial Comment

The difference in size between the two tires is very little. It is 5% (55-50=5) times the width of 235mm, so it is just under 12 mm. It doesn't seem likely that this would cause a problem on your 2008 Chevy Equinox, but it is wise to try a test fitting in the most restricted area (usually a front wheel well) to be sure before mounting all the tires and committing to using them.

235/75r16 vs p225/75r16 tires

is replacing 4 p23575r/16 with p22575r/16 tires accepatable for a 2006 chevy trailblazer OK?

This is temporary solution till get enough to purchase all new.

Editorial Comment

See our Tire Size Calculator and type in these two tire sizes and you'll see that the 225/75 r16 tire is just slightly smaller in diameter that the 235/75 tire.

The difference is less than 2%, so it falls within what I consider to be an acceptable range for a tire swap.

Sometimes people will choose a different size because their original size is hard to find or much more expensive than a more popular alternate size.

Tire Concerns: 195/60/R14 vs 195/70/R14 for 2000 hyundai elantra

by K_Iarussi
(Montana)

Can I put tires that are 195/70/R14 on my 2000 Hyundai Elantra? The tires are a bit higher right? Would that affect my car any? Want to make sure it is safe for both me and my car.


Editorial Comment:

Unless you are making an extreme difference in tire sizes, there is rarely an issue of safety when changing tires. The things that might affect the safety is when you change from a tire rated at a certain speed or load rating to another, especially when you are going from a high rating to a lower one.

When you change tire sizes the things that happen are mostly to do with power, fuel consumption and speedometer accuracy. Another issue … mostly noted when you increase the tire size is whether or not it will fit inside the space available and will not rub either in normal use or when turning.

To compare the first three issues use our Tire Size Calculator and if space seems to be a problem… do a test fitting first to make sure no rubbing will take place.

switching tire sizes

I have a 2007 Hyundai Santa fe with summer tires 235/70R/16 and I have four brand new winter tires I would like to use but they are 225/60R/16's. Is it okay to use them or will they damage the car in any way

Editorial Comment:

Since you are staying with the same sized rim, these tires would work on your vehicle providing you with less clearance, but they are not a swap that I would recommend because they are far beyond the 2% difference in size that I generally recommend. The difference, in fact, is more than 8%, which means a considerable speedometer error and increased fuel consumption. Would it be worth your while to spend nearly 10% more in fuel?

Tire Concerns: same tire size with different wheel width

by Steve G
(Wichita Falls TX)

I recently installed 4- P235/75R/15 on 15" oem steel rims
then realized the front rims are 8" wide but the rear rims are 7" wide. What effect will this have on vehicle tracking properly? What about offset? Should I put the 8" rims on thr rear? Do all rims have to be the same width. This is on a 1998 chevy 1/2 ton extended cab 2wd.

Editorial Comment

I'm not aware of any problems in using different width wheels on the front and back of a vehicle. Both these wheels are within the allowable range for a 235/75 tire, so there is no big issue as far as the tire is concerned.

I would be inclined to keep the same width of wheel on both the from and the back … that is don't mix widths on the same axle, but I would personally want to try mixing them on an experimental basis just to see how they felt. As long as the tire pressure is kept constant I don't believe you'd find much difference, no matter what the position of the particular wheel was, but perhaps in practice there might be some differences.

tire sizes for 2005 Lincoln

by john

I have a 2005 lincoln ls v8 with p225 50r 17, can i put p225 60r 17 with no problem.

Editorial comment

The change to a 225/60 r17 from a 225/50 r17 means you are putting a larger tire on the car. How much? (60-50=10) The new tire will be 10% of the width higher or 22.5mm which is just under one inch.

Do you have the space in your wheel wells to take a tire this is nearly 2" bigger in diameter? Besides this there is nearly a 7% difference in size which means you will have a marked difference in speedometer reading and lower fuel consumption offset by lower power transfer to the wheels.

235/65R16 tire the same as 235/60R17

by Dwight
(Lloydminster)

On a 2006 Chev Equinox with both a 235/65R16 tire with a 16" rim and a 235/60R17 tire with a 17" rim fit the same

Both tire are the same height just concerned that both rims will fit without affecting the brakes or anything.

Editorial Comment: If you will enter both tires into our Tire Size Calculator you will see that they are not the same. It's true that the difference is very small, and that in practice a difference this small can be virtually ignored, but they are definitely not the same.

Now the question of whether or not there will be any effect on brake operation depends on which wheel the Chevy Equinox is designed to use. If it is designed to operate with 16 inch wheels, there will be no problem installing larger 17 inch wheels because you will be providing more space for the brakes. If, however, the vehicle is designed to use 17 inch wheels and there is no extra clearance provided then you might have a problem installing 16 inch rims.

My research suggests that 16 inch rims are acceptable for some models of the 2006 Chevrolet Equinox, but the only way to be sure is to try them. Make sure you have the same bolt pattern on both wheels.

185/70 r15 for 2003 Montana

by victor levi
(moncton nb canada)

Too small?

Too small?

There is 215 70 15 on the van now and now i got a set of 185s want to know if they will fit.

Editorial Comment:

Sometimes experienced tire professionals tell me they are surprised to read the questions which people ask here. To them, this question is almost the same as "I wear a size 10 shoe but I have these nice size 8 sneakers and wonder if they will fit…"

To be truthful, the comparison is not exactly valid, but in this case the 185/70 R15 tire is definitely smaller than the 215/70 tire. First it is narrower by 30 mm, which is what the first number tells you and you can see this by simple subtraction.

The second difference is not quite so obvious, but the height of the tire sidewall is nearly an inch shorter. How high is each tire? It is 70 percent (the second number) of the first and works out to be about 21mm, which is slightly less than one inch.

Unlike shoes, these tires would fit on the wheels of the Montana, however, because of the height difference the vehicle will sit that much lower on the ground. Also, the overall difference is sizes is greater than 6% which will affect the speedometer reading and fuel consumption by about this amount.

We normally do not recommend a user install tires which are more than 2% different in size from the OEM tires, and this certainly exceeds that difference so my advice is to NOT use these tires on this vehicle.

There isn't a great deal of difference between the two tires. You can check out the difference using our Tire Size Calculator. The 225's a a wee bit bigger and will show your speedometer reading wrong but will slightly improve your gas mileage.

195/65/r15 tires for 72 gmc half ton

Can I put 195/65/r15 tires on the front of my 72 gmc half ton 2wd pickup?

The tires in it are very bad and weather cracked. I can get some car tires for free and don't have money to buy new tires so I'd like to put the free one s if I can.

Editorial Comment:

Your vehicle is so old that I can't find specs for the tires on the internet.
If the car tires you can get for free are for the same rim diameter, then you are part way there, and even if they are the same width and height you still might have difficulty unless the tires are made to work with the same load and under the speed rating which your pickup requires.
There's little problem in using tires which are rated for heavier loads or higher speeds, but you are asking for problems is you use tires which are under-rated. These are the issues you must consider.

205 55r16 for 2010 Ford Focus

by Jeffrey

2010 Ford Focus

2010 Ford Focus

My car came with 205 50 R16 tires but was wondering if i could put 205 55 r16 tires on a 2010 Ford Focus without hitting fenders or struts.

Editorial Comment:

You are probably aware the 205/55 tires you are considering are larger than the originals, or else you wouldn't be asking the question. What you may not be aware of is that, you can simply calculate the difference by multiplying the difference of 5 by the width, then divide by 100. This gives you an increased sidewall height of 10.25mm, which is just under 1/2 inch.

This difference might not seem much, and it is highly likely that this difference will fit within the space that is available without rubbing but the only way to be absolutely sure is to try a test fitting. I cannot emphasize this enough, even if you have a friend tell you they have exactly the same car and this works for them.

I had a customer who had a vehicle which used larger tires at one time come in to have that same larger tire put on his vehicle again. They wouldn't fit without rubbing. What had happened is that he had done some mechanical work on the car over the previous year (I forget exactly what it was but it had something to do with the suspension or steering) and when the tires were tried this time, they would not work.

Apart from what I've just stated I do not recommend this swap for your vehicle because the difference in size (you can use our Tire Size Calculator to discover this) is more than 3%. I normally do not recommend any variation exceeding 2% for a good match, so I would suggest you reconsider.

advantage or disadvantage of tire size 15 vs 17

by Don
(Lakewood Calif.)

New car came with 17 wheels, should I trade them in for 15?

Editorial Comment:

This essentially boils down to an examination of low profile tires (the 17s) against the high profile 15 inch tires.

There seems to be a trend in recent years to newer cars being sold with lower profile tires than in previous years.

Whether or not this is justified by performance depends on a number of factors including: ride comfort, looks and performance.

It has been argued that cars use low profiles for racing but this is not universally true. Notice Formula 1 cars, Nascar, and drag racing and you'll note that the tires they use are not very low profile. There is a certain amount of sidewall flex which helps in performance. If a car hits a strip with ripples and have low profile tires the car may bounce causing a possible loss of control.

Apparently a group In Australia tried a high performance supercharged v8 on a track with 22 inch wheels and with 19 inch wheels and concluded that the 19 inch wheels were faster by 2 seconds around a short track and that the 22 inch wheels tended to slide, so traction wasn't very good.

I believe that the biggest argument in favour of them is perhaps the look they offer, but this is something that may change over time as consumer tastes change.

205/60/r15 for 2004 ford focus

Will 205/60/r15's fit on a 2004 ford focus originally spec'd with a 195/65/r15?

Editor's Comment

The difference between a 205/60R15 and a 195/65R15 is very small considering the overall diameter of each tire when mounted and inflated. The difference is a mere 1.18%, so for practically any viewpoint there would be no problem. The fact that the 205 is wider than the 195, would be a problem only in a vehicle where the space in the wheel well (particularly the front) might be very tight. If you have any doubt, try a test mounting first.

The only other consideration you need to be careful with when changing to a different tire is to make sure that the speed and load rating of the new tire is the same or exceeds that which you were using before. Often, when you go to a larger tire this is no issue, but it doesn't harm to check to be sure.

will a 235/60r15 rub on 2003 grand am

by shorty beasley
(castalian springs TN )

I JUST WANT TO SEE IF I CAN PUT THESE TIRES ON MY CAR .


Editorial Comment

You are considering putting 235/60 R15 tires on a 2003 Pontiac Grand Am.

The 2003 Pontiac Grand Am GT Sedan came equipped with 225/50 R16 wheels and there are some 17 and 18 inch wheels available for this vehicle with corresponding tires of 225/45 R 17 and 225/40 R18 suggested.

My first impression is that the 15 inch wheel may not leave enough space for the braking mechanism to work correctly on this car, but that may be determined by test fitting the wheels you have in mind, or if you already have been using 15 inch wheels with no problem then you are home-free on that issue.

If 15 inch wheels will work on your Grand Am then the other issue to consider is the end size of the installed tire. Using a 235 tire which is 10mm wider (about 1/2 inch) isn't usually a problem but you would be much better off with a 225/55 R15 to get a closer match in tire diameter. Of if you want a wider tire, then a 235/55 would be a much better choice than the 235/60. This latter tire is more than 5% larger than the original OEM equipment and for that reason I would not recommend using it.

2001 Mazda Protege - 195 55R15 vs 215 60R15

I have a 2001 Mazda Protege. Its current tires are size 195 55 R15. My husband has a spare set of brand new winter tires, already on rims, sized 215 60 R15. Are they compatible with my car?

Editorial Comment:

Your question makes me uncomfortable even before I try any calculations. I'll explain why.

Notice that there are three numbers in a tire's size. Normally, if you want to retain the best compatibility in switching tire sizes, if you increase one of the first two numbers, the other one should be decreasing. The effect of this opposite movement in numbers has the effect of possibly maintaining the over-all same tire diameter in spite of the changes in numbers. If both numbers go in the same direction (increasing or decreasing) then the end effect is to amplify the change and thus make it even more exaggerated.

In your case you are increasing both numbers and this does, in fact result in an increase in the tire diameter of 1.71 inches or about 7.3% bigger. Normally I recommend that there is no more than 2% difference in tire sizes when a swap is made. If not the difference produce too much of a change in performance, fuel economy and speedometer reading to be desirable for more people.

I do not recommend this swap for your car, even if the wheel bolt patterns match, it is not a good match of sizes in my opinion.

225/50 R17 in place of 215/60 R16

by Kam
(Summerville,sc USA)

2012 Honda Accord

2012 Honda Accord


I have 2012 honda accord LX with Steel wheel with 215/60 R 16 tire,
I like to get alloy wheel and one of the person has 225/50 R17.
Is it safe and ok to use different rim and tire?
Is their any problem rubbing etc.?

Editorial Comment:

There are two issues which I consider whenever thinking about changing rims and tire. First is the wheel match as far as the bolt pattern. If these match up, that first issue is out of the way and you can then consider other matters. If the wheel bolts don't match, nothing else matters because you'll never get them on your car.

Next you need to see if the overall size of the new tire, when mounted, differs very much from your original size. You can do this using our Tire Size Calculator. From this I see that there is less than 2% difference in size ... the larger tire and wheel being just 3/10th of an inch bigger. I don't think this is enough to likely produce any rubbing or friction, but the only way to know for sure is to do a test mounting, usually in a front wheel so you can try out the steering and wheel movement to make sure there is no obstruction.

Since the wheel is larger than what you started with it would not be likely you'd have a problem with interference in your brakes, which could be an issue if you were putting on smaller wheels.

You will have a slight speedometer error but since the real speed will be slightly less than what is shown, that shouldn't be anything to worry about.

245/55/18 or 255/60/18 for 2011 malibu ltz

by Jeff
(Omaha, NE)

I have a 2011 malibu ltz 4 cylinder. I have 18 inch wheels that are currently 225/50/18 and have an opportunity to purchase blizzak tires, but they are a different size. will they fit on my rims without rubbing?

Editorial Comment

225/50R18 is the standard OEM size for the 2011 Chevy Malibu LTZ.

The first tire you ask about 245/55R18 is already 6.52% larger than the original and this is far beyond a 2% limit that is recommended for tire swaps. The 255/60 is even bigger so it is an even worse choice.

Check our Tire Size Calculator to see what alternative sizes are within the 2% limit (there are several possibilities) and it is likely that you may find a size which is available in the tire you want.

Different sized tires for Dodge Ram 2500 van

by Shannon
(MA)

My 2001 Dodge Ram 2500 van takes 225 R75 16 tires. Can I use 265 R75 16 tires/rims from a 2001 Dodge Ram truck?

Editorial Comment:

My research shows me that a2001 Dodge Ram Wagon B2500 a 2001 Dodge Ram 2500 Reg Cab 4wd both use the same wheel and tire size as OEM. They each use 245/75 R16 tires and the wheels have Offset of 00mm, Backspacing of 4.44" and a Bolt Pattern of 8-165 so, if we were starting with original equipment from these the swap might work.

5But you say the tires are 265/75's on the truck and that you now have 225/75's and this concerns me. I suspect that one or both of the vehicles may have different wheels, since the 225's are considerably narrower than the 265's and each these tires would have an recommended rim of a different width. So what you need to learn is the narrowest rim which the 265's would permit and see if this is what you now have, unless you are planning to change wheels, too.

That being said, your existing tires may not be the best for the vehicle if they were sized downward because they are nearly 4% smaller than the OEM, yet the other ones, the 265's are nearly 4% bigger. Both of these differences are considerably more that what I recommend people to accept, and when you go from 4% less to 4% more you have an enormous difference which is over 8% and this is far beyond anything that I would call reasonable.

I don't know what your motive is for making this swap, but if it is just because you have these other tires available, then I would recommend you don't do it … you are not likely to be pleased with the results and because of the considerably larger size of the 265's you may not even have enough space for them to work since you are looking at tires which are 2.36 inches larger in diameter that what you now have.

225 60 r16 tires for 2003 honda element

by Roy Green
(portage, indiana, usa)

can I put 225 60 r16 tires on my 2003 honda element ?

I want to know if it would be a good tire for the element. I have little money and these tires are available cheap from my friend

Editorial Comment:

The tire you propose to use is smaller in overall diameter than the OEM size of 215/70R16 even though it is slightly wider.

Because the diameter is smaller your speedometer reading and curl consumption will be affected by over 4%. I normally don't like to recommend a difference of more than 2% but you may find that the extra fuel cost that this will produce is worthwhile for you.

Make certain, however that both the load rating and speed rating on the alternative tires are the same or even greater than your original tires or you may be facing a safety issue, too.

Can a 195/70r14 size tire fit on a 1993 Hyundai Elantra?

by Segun
(McLeansville, NC, USA)

A 93 Hyundai Elantra normally calls for the tire size 185/60HR14

Editorial Comment:

This is not a good swap because both of the first two numbers in the size are increasing which means that the 195/70 r14 will be considerably larger than the 185/60 r14.

The normal "rule" when changing tire sizes is that if one of these two numbers increases the other one should be smaller, and this is not the case, so even without doing any calculations I am sure that this is not a recommendable swap.

Doing the actual calks. shows that the difference in sizes is more than 8% which is far beyond the limit of 2% which I normally consider acceptable.

Do not consider this swap further.

Tire Concerns: Larger winter tires on SUV

by edgar
(ontario canada)

I have an SUV with 215/65 R16 96H Bridgestone® Dueler H/T687 M+S All-Season tires on them

I got a really good deal on a new set of winter tires:
225/70 R16 M + S

Can I fit them on to my SUV?



Editorial Comment:

The new tires you bought are larger in diameter than your originals. They are 1.40" bigger which means that your true speed will be 105.18% of what the speedometer shows but, the good news is that you could expect a 4.9% improvement in fuel consumption.

As long as you have enough room in the wheel wells to accommodate the larger size, there should be no other concerns.

Tire Concerns: Different sized tires

My car needs new tires all the way around (205 /60R15)and I happen to have a set of 4 tires that are almost new from a car that I owned previously(195/60R15). I was wondering what would happen if I were to cheap out and use the tires I have sitting in the garage.



Editorial Comment:

These other tires are lower and narrower than your present tires. The difference in width is 20mm (about 4/5 of an inch) and the height drops by 60% of that which is about 1/2 an inch. I can't think of any significant difference a slimmer tire will make and a half inch lower height is not great either but could result in some minor driving issues with slightly reduced clearance under your car.

Replacing 205/55/R16 tire with 225/55/R16

by Gary Sheppard
(Waterford, CT. 06385)

My car is a 2001 Mitsubishi Eclipse GS 4cyl. My OEM tire size is 205/55/R16 and I got a really good deal on 4 new Michelin Ice-X 225/55/R16 tires and want to put them on my Eclipse. Is this plausible or a bad idea?

Editorial Comment:

You wish to install 225/55 R16 tires on the existing wheels of a 2001 Mitsubishi Eclipse, which came with 205/55 R16 tires.

I'm sure you are aware that these tires are wider by slightly under an inch, and because of this they are also slightly higher which gives them a greater diameter.

Although the increase of about 8/10ths of an inch may not seem like much and there may be enough space, but the difference is more than 3% which is greater than we normally recommend when swapping tire sizes. You can expect to use about 3% less fuel and the speedometer will show that you are travelling about that same percentage slower than you actually are.

265/70 R16 tires for 1999 Lincoln Town Car

by Dayna
(Beaumont, TX)

Lincoln Town Car

Lincoln Town Car

The factory tires are 235/60 R16. I have an opportunity to get 4 rims and tires 265/70 R16 for a great price and don't know if they will fit the car.

Editorial Comment:

Even without calculating the tire sizes I suspect that this is not a great swap because you are wanting to increase both the tire width and the tire aspect ratio which will make the tire height increase even more.

The usual advice when you swap tire sizes is to either increase the tire width or the AR, but decrease the other one to compensate and attempt to end up with more or less the same total tire diameter -- or at least within about 2%.

In your case there is more than a 12% difference, or 6 times what we like to recommend. You will have an enormous speedometer error and a reduction of power. With an almost 2 inch difference in total tire diameter you are likely to have the tires rub if they will even fit in the wheel wells.

I do not recommend this swap.

Tire Concerns: 215/60r16 in place of a 225/50r16

by James
(Iowa)

My transmission went out of my 2000 ford taurus i have new tires on it that are a 215/60r16 i plan to scrap the car i have bought a 2000 grand am gt that needs tires the 225/50r16 i know it is only recommended that i use the same size but there really isnt much of a difference in sizes its only like 1.2 inch difference so is it possible to use them.


Editorial Comment:

Whenever you move to a larger diameter tire the most common complication is the possibility of rubbing when you corner or the car passes over bumps and dips a bit.

In your case, there is a size difference of over 5% which is beyond the range which I generally recommend to stay within if you are swapping tire sizes. If the tires you now have are in excellent condition, you might be better off in seeing if you can sell them or swap them for a size which is more closely matched to the Oem size for your vehicle.

Use the Tire Size Calculator to find a better match.

P215/65r15 tires for 1996 buick century

by steve wright
(minto nd united states)

1996 Buick Century

1996 Buick Century

my 1996 buick century 4 door has 185/75r14 tires on it and i want to put on 215/65r15 tires.

Editorial Comment:

If you want to put 215/65R15 tires on your 1996 Buick Century, I hope you are aware that you are going to have to get a new set of wheels, because there is no way you can use 15 inch tires on 14 inch rims.

Apart from that, these wheels are a bit beyond what I normally recommend for a tire size swap. Normally I do not recommend a difference in overall size more than about 2% and in this instance the proposed tires are more than 4% larger. This is going to produce a speedometer error and may result in a decrease in fuel consumption at the cost of a lesser amount of power being delivered to the wheels.

If you're determined to go to a 215 tire width, a 215/60 would be a better choice, but for my thinking 195/65R15 would be a better size and would minimize any concerns about excessive tire width.

Can you replace a 225 65R 16 with a 225 75R 16 Tire

by David
(Schenectady NY)

I have a 2010 Chrysler T&C which currently has 225 65r 16. I was looking to see if I could use 225 75r 16 tire safely and not reduce gas mileage or mess up the speedometer. Can this be done?

Editoria Comment:

In a word, the answer to your question is NO.

The 225/75R16 is larger in sidewall height than the 225/65R16 by 10% of 225 mm. This will produce a bigger tire in overall diameter which will INCREASE gas mileage because each time the tire rotates it will travel a bit further than the smaller tire. But it will also affect the speedometer for the same reason and you will actually be travelling faster than what you see on the speedometer.

See our Tire Size calculator to find out the exact differences if you are interested. You can also use that to find alternate tire sizes (either wider/narrower or higher/lower profiles) that will keep you fairly close to the same mileage and speedometer reading as you now have.

Tire size for a 2002 Honda Accord.

by jason
(maple ridge BC canada)

Will a 215/65r/17 tire fit a 2002 Honda Accord se coupe

Editorial Comment:

The OEM tire for a 2002 Honda Accord SE Coupe is listed by Tirerack as 195/65R15. For 17 inch rims they suggest using 205/50R17.

With the optional size they caution you that the optional sizes they list are expected to fit most vehicles when using proper wheels.

They go on to say: "General vehicle condition, vehicle and wheel application can affect proper tire fitment. Optional sizes should be carefully tested on a vehicle and clearances with the body work and suspension should be checked prior to driving on a tire. Failure to do so can cause damage to the vehicle and/or sudden tire failure due to tire damage caused by contact with the vehicle."

Good advice to follow.

2002 dodge grand caravan sport tire size

by Jackie
(Connecticut)

2002 Dodge Grand Caravan Sport

2002 Dodge Grand Caravan Sport

I have a 2002 dodge grand caravan sport with tires that are 205 55r16. Can I put tires that are 215 65r16 on the vehicle? Would there be any issues with doing that?

Editorial Comment:

This is a swap which I would not recommend because the 215/65R16 tire is more than 8% bigger than the 205/55R16. Normally it is not a good idea to swap to tires which are more than 2% different in size than the OEM tire.

The issues you will face in doing this will be a definite error in your speedometer reading, and a decrease in fuel used at the cost of a substantial reduction in power available to the wheels. You may also have problems in rubbing of the tires against the vehicle because of their increased size.

As a rough rule of thumb, when you increase one of the first two numbers in a tire's size, you should decrease the other number. This may compensate for the differences and keep you within the 2% range. If both numbers change in the same direction you don't need a Tire Size Calculator to tell you the exact difference because you will invariably be out-of-range.

In your case a 215/55R16 would work fine because the difference in height produced by putting on a wider tire isn't enough to need to reduce the AR to a number lower than 55.

How do I convert antique tire sizes like 30 X 5 to modern tire sizes

by Eric Moore
(Matthews, NC, USA)

Is there a chart for the old original tire sizes that were a two digit number, then an "X" then a single number, such as 30 X 5, or 32 X 6, etc

Editorial Comment:

As far as I know, we are the only place where you can find a Tire Size Convertor that will do what you want, however, it's use is limited to tire sizes which are still being used, and not antique tires.

You could do the conversion manually using old tire sizes which are not included in the converter if you keep in mind that the old sizes are telling you the Tire's inflated diameter, and the tire's width in inches.

The current standard sizes give you the width in millimetres, the aspect ratio, which also allows you to calculate the height of ONE sidewall, and the rim diameter in inches.

To do the conversion manually, first subtract the tire's diameter from the rim's diameter. This gives you the height of TWO sidewalls. Divide this number by 2 and convert it to mm (multiply by 25.4). Save this number. Next convert the tire width to millimetres, again by multiplying by 25.4. Take the first number you calculated and divide it by the width in mm, and this will give you the Aspect ratio (AR) which is the second number in conventional tire sizes. The first number you calculated is the first number in a conventional size and the third number you already know, in inches, is the rim diameter.

Of course the aspect ratio is not likely to be be an even number which ends in 0 or 5, as modern tires use, but you will have the approximate equivalent size, and if you are looking for the equivalent size from a tire now made you'll have to round your AR up or down a bit.

Wrong tires size

by brandon wilcox
(fernley nv usa)


On my 99 dodge ram 1500 2wd truck i have 26575r16 tires but the origanal size is 24575r16 what can happen?

Editorial Comment:

When you provide a limited amount of information the only thing we can do is speculate.

Since this is a 1999 vehicle and it apparently is still running satisfactorily, the quick and dirty answer to your question is that nothing worth worrying about is likely to happen.

Of course, we don't know if it has always had these other tires on them, or if you have always been the owner, nor do we know if there has been any modifications or major work done that may have been related to tire caused issues.

Because the tires you mention are slightly larger that the OEM tires, this means that with them the speedometer will read approximately 4% less than the reading with the regular OEM tires. Also because the tires are larger, the vehicle would be using that same percentage less fuel.

I rarely recommend that people go for a difference of more than 2% when swapping tires, but if you have been driving this vehicle with these tires for any length of time, are happy with them and are accustomed to them, I see no reason to urge you to switch back to the originals if you don't want to.

p225 70/R16 vs p205/60R16 tires

i have p225 70/R16 tires on my truck can i put p205/60R16 on to replace them.
I have a toyota tundra 05 truck. My friend has tires off a car in his yard. i need tires but the numbers are different.

Editorial Comment

Are you kidding?

Your question is something like a person who walks into a store and wants to buy something that has a price of $125.00 and who goes to a sales clerk to ask if they can buy it with a bill which has the numbers $50.00 on it.

Of course the numbers are different! The numbers are telling you the size and because they are different the size is not going to be the same.

There are 3 parts to a tires size: the width of the tire which is the first number, the height of the tire, measured from the rim of the wheel to the tread of the tire (the second number), and finally the diameter of the wheel on which the tire is to be installed.

The only thing which is the same in your case is the wheel diameter. If this were different you could literally kill the person installing the tire on the wheel in an extreme case or run the risk of having a very unstable tire on the vehicle that could come off at any time when it is out on the road.

Leave your friend's tires in his yard and look somewhere else for the same sized tires that your truck needs, but do not use these on your truck. Apart from being far too small, they may not be sturdy enough to carry the load that your truck tires are designed to carry.

It seems to me you might not even have the right tires on your truck right now. To start, I'd suggest you go to an online tire dealer (like tirerack.com) and do a search for the tires they recommend for your vehicle. Using those recommendations shop around for the size they recommend to find a deal you can live with.

30x9.50r15 tires on 95 tacoma stock rims

by Matt
(Middletown, NY)

Can I put 30x9.50r15 tires on my 95 tacoma stock rims?

Right now it has 31x10.50r15

Just wondering if changing tire size from 31x10.50r15 to 30x9.50r15 would make any difference and if it can be done. I think it can but I don't want it to become dangerous..

Editorial Comment:

I have to admit that your question has me stumped and I can't give you a definite yes or no answer because I don't have all the specs on either of the tire sizes you mention.

Both tires will likely fit on the stock 15 inch rims, but that doesn't mean it is a good idea. What you need to take into account is the rim WIDTH which each tire is designed to be used with.

All tires are designed to be used with one specific rim width, but have a range of permitted rims which are roughly 1/2 inch narrower and 1/2 in wider than the ideal rim size.

To the best of my knowledge, the rim width which the 31x10.5r15 tire uses can be from 7 to 9 inches, which suggests that 8 inches is the design width. If this is your vehicle's rim width, I believe the 30x9.5r15 tires will work because their range seems to be from 6.5 to 8.5 inches, so an 8 inch rim (or even a 7 or 7.5 inch rim) is still inside the acceptable range.

If you want to be absolutely certain about the fit you need to get the manufacturer's specifications for the tires you want to use and see if their permitted rim widths includes the size you now have.

Larger tires for 1986 Toyota 4 Runner

by Randy
(Marietta, Ga)

1986 Toyota 4 runner

1986 Toyota 4 runner

What's the largest tire I can put on a 1986 toyota 4runner with 15 inch wheels?

I am wanting to put as wide and tall of an offroad tire on my 4 runner without having to lift anything.

Editorial Comment:
Without examining your 1986 Toyota 4 Runner first hand and possibly trying on a few alternatives I can't give you an exact answer, but I can give you some ideas as to how to go about choosing a larger tire.

First you will want to check places like Tire-rack.com to find out what are the largest 15 inch tires that are available. After all, if a tire isn't available, there's no point in pursuing it.

Next do some measurements on you vehicle and see how much extra space you have between the tires you now have installed, and the body of the vehicle. Look for the spaces where there is the least about of space because these will be the areas where your limits are imposed on you.

Get you vehicle on a vehicle lift and turn the steering wheel to the extreme left and right side and see how much space you have on each side in the narrowest spaces.

Once you have an idea of the free spaces which you have available you can then see how much tire you can "add" to you existing tire before you will be rubbing or hitting something.

Then you can use our Tire Size Calculator
Tire Size Calculator to find out the dimensions of your existing tire and compare it to the possible sizes which you might like to try.

Remember though, that just because you might get a tire installed, it's actual behaviour when you start driving might change because of the amount of weight you have in your vehicle at any given time, and the movement of the body as you go over dips and bumps, and the sway when you turn from side to side, so you'll have to make final modifications in your choice taking into account these considerations.

Hopefully this will give you enough ideas to get a solution you're happy with..

Can I put smaller tires on my car?

by Arica
(Missouri)

2000 Chevrolet Impala

2000 Chevrolet Impala

I have a 2000 Chevy Impala with P225 60r16 tires. Is it ok to put 205 55r16 tires on it? What issues might I have if I switch to a smaller tire size?

Editorial Comment:

I hate to have to tell you this but Chevrolet discontinued the use of the 55 Aspect Ratio in 2008.

Just kidding! As far as I am aware your Chevy Impala can use virtually any aspect ratio that you want as long as it creates no problems with clearance or other operating systems.

As you know the 225/55/R16 tire is smaller than the 225/60/R16. The actual difference in diameter can be calculated and is 3.33%. This tells me that you will experience an error in your speedometer reading of 3.33% and also that you will use about 3.33% more fuel because each wheel will only cover 3.33% less distance on each revolution.

Because the tire is slightly smaller (0.44 inch) the car will be that much closer to the ground and if clearance is something that you are concerned with, this would be a reason to be more concerned.

Normally I don't like to recommend that anyone makes a swap to a tire which is more than 2% difference in over all size, and you can see that this is beyond that limit. If you wish to stay within my suggested limits either 235/55/r16 or 255/55/R16 would meet those requirements.

20 inch tire and wheels for 66 mercury cyclone GT.

by marion

66 Mercury Cyclone GT

66 Mercury Cyclone GT

can i fit 20 inch tire and wheels onto 66 mercury cyclone GT.

I would like to know if I could fit some 20 inch tire and wheels onto a 1966 mercury cyclone gt.

Editorial Comment

Providing you find the correct wheels which will fit the bolt pattern of your car, the key to fitting 20 inch tires to your vehicle is choosing lower profile tires using the Up-sizing principle of using lower profile tires so that the resulting over all tire diameter is virtually the same as your original tires. A very rough rule of thumb is to reduce the AR (aspect ratio) by 5 for each inch of extra diameter which you add to the rims.

As I mentioned this is a very rough rule … better to use a tire size calculator such as the one we have on the website to compare your original tires and choose a size which will keep the ending diameter within 2% of your starting point.

If you go beyond the 2% limit, you are starting to get into the "Experimental" range and must be prepared to accept consequences which are beyond what a normal driver would experience in their car.

1997 saturn sl2 tires

by joseph
(bolton, ma)

Is it okay to put 195 60r 15 snow tires on front and have non snow tires in rear 185 65r 15.

Editorial Comment

You wish to put 195/60R15 snow tires on the front and use 185/60R15 regular tires on the rear.

I normally don't like to see people mixing tire sizes on a vehicle which is not designed to use mixed tire sizes. One of the major issues in my mind is the spare tire. What are you going to do if you have a flat. It is never advisable to use two different sized tires on the same axle because this can provoke extremely difficult handling problems.

205/60/R16 in the front and 225/60/R16 rear

by Maria
(Dallas, Tx)

2006 Toyota Camry

2006 Toyota Camry

I have a Toyota Camery that needs tires in back. I have 205/60/R16's on it now, all four tires. I have a set of new 225/60/R16 off another car. Can I put these on the back or front of my car with the other size on there as well?

Editorial Comment:

The Toyota Camry has been made and sold since 1982 til now, and you haven't told us the year of your car so I have no way of knowing whether or not the tire you have on now is even the correct tire.

Even within the Camry model there are quite a number of variations which may have had different sized wheels and tires depending on the year of production. For the sake of this discussion I have selected the 2006 simple Camry model.

The 2006 Toyota Camry came with 205/65 R15 tires as standard equipment and as an alternative 205/60 R16 tires have been offered, which is the size you now have.

You're wondering if a 225/60 R16 tire will fit. Chances are that this tire will fit on the wheels you now have, but that may not be a good choice because this tire is not only wider but also higher. In fact it is more than 3.5% larger which translates into nearly one inch. In an emergency this might be a suitable substitute until you could get a replacement at the nearest dealer, but it is not a swap that I recommend.

If you wish to instal only two you must make sure that the same sized tires are always installed on the same axle, but what are you going to do about the spare tire? Are you going to carry two spares because you don't know which one will fail? And if you have mixed sizes, front and back, this also complicates the situation when it comes to rotating your tires to even out their wear and get maximum mileage from them.

My suggestion is that you avoid this swap because these tires are far beyond the maximum 2% difference in size that I recommend when changing tire size. Sell or trade the tires you have acquired and get the same sized tires that are currently on your car.

Replace P225/55R16 tires/wheels with P215/65R17/wheels

by Danny
(Kingwood, TX USA)

Well this work on a 2002 Ford Mustang? Going from the stock 16 wheels with P225/55r16 tires to 17 wheels with R215/65r17 tires. Bolt pattern for wheels are the same and positive off set.

Editorial Comment:

The problem with what you propose here is that you are ending up with tires that are almost 9% larger than you started out with. (Use our Tire Size Calculator to see the exact details.)

Ideally you need to apply a principle called Plus Sizing which aims at retaining the same overall tire diameter after you have switched wheels in order to avoid any changes in speedometer reading, fuel use, power transfer, and issues that might result in the tires rubbing or being interfered with by the car's structure.

In the case you are considering you should be reducing the tire's aspect ratio from 55, rather than increasing it. An example of a good fit would be a 225/50R17, if you want a slightly wider tire or 215/50R17 for the same width.

Of course you also need to pay attention to the load and speed ratings on your new tire. Always stay with the same ratings or higher ratings to avoid problems.

225/60/r17 tires for honda cr-v 2009

by frank
(carson city,nv.)

my tires on my honda 2009 . are 225/65/r17 (102)

will a 225/60/r17 (98T) fit the honda?

Editorial Comment:

Presuming that your 2009 Honda CR-V had 225/65R17 tires as OEM tires then there shouldn't be any major difficulties because the 225/60 R17 tire is slightly lower. In fact it is precisely 5% of the width lower (65-60=5) and that is just a bit under 1/2 an inch, or 11.25mm. The width, of course is exactly the same.

What can you expect from this difference? In having a smaller diameter tire, each time the tire rotates you will travel slightly less distance than you would on the original tire, so the speedometer will show a speed that is faster than you are actually travelling, and because you need more rotations to travel the same distance, your fuel consumption will go up by the same amount as the speedometer error.

245/50/ZR19 tire vs 225/55/R19

by Ken
(Hillpoint WI)

can you substitute a 245/50/ZR19 tire for a 225/55/R19?

2010 Dodge Journey AWD SXT only one source - Kumho - looking for an all weather sub

Editorial Comment:

It might surprise you to learn that the 275/45-19 is exactly the same diameter as the 225/55 R19 and the 245/50 ZR19 is just slightly lower, but so little that you'd hardly notice the difference in fuel economy or your speedometer reading.

The "Z" in the tire size refers to the speed rating which is higher than the tire without the Z so, there is no issue there, either.

If you think you have a good reason for making the switch, I'd venture a guess that you won't find any problems with making this change.

265/70 R15 vs 31x10.5 R15 tires

by Venn
(Antipolo, Philippines)

Is changing from 265/70 R15 H/T 11S bridgestone dueler to 31x10.5 R15 AT/SA feasible? advantages and disadvantages?

I have a 2004 Ford Everest 4x4 manual with limited slip differential. The manual that came with the unit says that the exact size of the tires should be the same. The tires which came with my unit was a bridgestone dueler 265/70 R15 112S H/T 689.
When I went to a tire dealer, they said that a 31 x 10.5 R15 wrangler AT/SA would also be good on my unit.
I drive quite far every week and would average around 5,000 kms per 3 months. I am concerned on the safety, first and foremost, and on subsequent priorities are durability, stability and fuel economy.
I am from the Philippines and generally have a tropical climate and have occasional flooding, so traction on wet roads is also a concern.
Furthermore, could you suggest tires which would be a good replacement for my more than 8 years tires.

Editorial Comments

If you were to check our Tire Size Convertor, you would find that the 31X10.5 tires are the equivalent to a tire that would be sized at 267/76 R15.

Of course there is no such tire, so the closest existing size to that would be 265/75 R15. This would be just slightly larger to the tire you have been using. In fact the difference is more than 3.5% and it is a different which I normally do not recommend for most tire users … the maximum difference I like to suggest is 2% or less.

The issues you will face if you do make the change is that your vehicle will use less fuel but there will be a speedometer error … both of about 3.5%. I doubt if there will be a problem with space for the tires to function properly and as long as you keep all the tires the same size you will not have any issues because of the 4X4 capabilities. Make sure, however, that you do not mix tire sizes if you use the 4X4 … so you'll also want to change the size of you spare tire.

1993 Ford Ranger Tire size

We are wondering if 215/70/R15's will fit on my sons 1993 Ford Ranger (2wheel)? It has had R14's but we want to put on bigger tires so we plan on getting tires and rims.

Editorial Comment:

Usually you seldom have problems if you use larger sized rims on any vehicle as long as you get rims which have the proper bolt pattern to match your vehicle. This is different from putting on a smaller rim which might conflict with the brakes which are inside the wheel. Extra space doesn't produce this problem.

Normally when you get bigger rims, you will switch to a lower profile tire so that the total operating diameter of the new tire is the same, or very close, to the original tire. This is called Plus Sizing, in the trade.

Check our Tire Size Calculator (see the links below) and choose a tire size which is no more than 2% different in over all size from your original tire and you should be quite OK.

Tire Concens: P205/65R15 92S vs P195/65R15 89S

by Lazette
(texas)

will P205/65R15 92S fit on a car made for P195/65R15 89S

Editorial Comment;

These tires are fairly close in size, the 205 tire being just slightly more that 2% larger, so fit won't be much of an issue. The 92 is a higher load rating and the speed rating of S is the same.

The only issue is the fact that you will have your speedometer read slower than you are actually traveling and you will use a bit more fuel (about 2%) Since the sidewall is only about 1/4 inch higher, it is not likely that you will have a problem with space (i.e. rubbing) but you are wise to do a test fitting before committing to this change.

65 vs 60 Aspect Ratio

by Louise
(Columbus, OH)

I have a 2008 Chrysler Town and Country, touring minivan with 121K miles.
In the process of replacing two bald back tires I realized the manual calls for 225/65R16 while we have four 225/60R16 tires on the vehicle.

It was purchased through an auction last year. And it never occurred to me to check the size of tires when purchasing!?

What advantages do see for buying 4 new tires with the 65 AR that the vehicle calls for
vs matching the 2 still decent tires with the 60 AR already on the van?

Editorial Comment

By returning to the original size you will get a slightly better fuel economy because of the larger tire and your speedometer will read accurately, while you now have a slight error.

Also by putting all new tires all the way round you will be starting fresh with your tires and if you do regular rotation you will get a better long term mileage out of these new tires. You might keep the two older tires to use as spares if they are in better condition that your spare.

I do not recommend that you mix tire sizes for regular use (in a temporary emergency situation OK), because this does cause complications when you are doing rotations.

If you are going to change only two, then I'd recommend you stay with the same size unless you are unhappy with the way these are performing.

99 honda accord ex - putting 215 R70/15 on instead of OE

as I recently purchased the 215 michelin defenders for a vehicle that is to be sold, i'd like to keep the tires to replace the 01 195s currently on the Honda.

will they fit underneath it without jeopardizing the safety?

Editorial Comment:

You would be better advised to sell the tires with the car you want to sell and use the cash to buy the right sized tires for the Honda Accord. 215/70 R15 tires are far too big to be a suitable substitute for OEM tires on this vehicle.

215\75R14 tires for 1989 Chevrolet S-10 2WD pickup

by Jim
(Reno, NV)

will 215\75R14 tires fit on my 1989 Chevrolet S-10 2WD pickup with out problems?
My truck came with 195\70R14 tires & the alternate is listed as 205\70R15. I have been given a full set of 215\75R14 tires mounted on rims, haven't tried them out yet but want to know if there would be a problem running them on my pick up.

Editorial Comment:

At first glance, I don't have a good feeling about this swap. The reason is that both the first two numbers in the tire size you propose are larger. Normally, for swaps that I would be comfortable with, if one of the first two numbers increases, the other one should decrease (or maybe stay the same, if the change in the changed number was small).

Using our Tire Size Calculator I see that the tire you asked about is 7.87% larger than your existing tire. My usual limit is 2% difference, beyond that limit you start to notice performance issues, speedometer errors, etc which are often not convenient.

Another issue you need to take into account when offered tires already mounted on wheels is if the bolt pattern of the rims is the same as your vehicle's. A very small difference can make it impossible to install the wheels, but you might remove them and put them on your other wheels provided that the last number in the tire size (14 in this case) is the same.

You might also consider if the speed rating and load rating of the tires is equal to or greater than that you have been used to use. Being over rated causes no problems, but if the ratings are lower you might be faced with problems that you could have avoided.

Will p195/70 r14 fit my 1987 BMW 325e?

by Jim Miller
(Everett WA)

The BMW has p185/60 r14 mounted now.

Editorial Comment:

The recommended OEM tire size for the 1987 BMW 325e, is 195/65 R14 so this is the ideal size according to the car's design specifications.

The 195/70 R 14 is a slightly higher tire than OEM and will make the speedometer read about 3.2% higher than it would with original tires but will use about 3% less fuel.

On the other hand the 185/60 tire you now have mounted is over 5% smaller and is showing a speed which is 5% less than it should and is using about 5% more fuel than you need.

So the difference between the 185/60 and the 195/70 is very big. Your real speed will be more than 8% higher than what would show with the tires now installed but you should have a decrease in fuel use by that same percentage.

My recommendation is that you go back to the original OEM size of 195/65 rather than the 195/70's you asked about. This will give you the performance more like the car was designed for.

Change of tire size on Ford Ranger

by Dan
(miontreal, Canada)

2010 Ford Ranger

2010 Ford Ranger

Is it safe to install P225/55/17 on a Ford ranger 2010 4X2?

Editorial Comment:

According to the specs I have available the 210 Ford Ranger has a standard tire size of 225/70R15. If your size is different from that my conclusions may need to be modified.

To start, as long as the bolt patterns match you shouldn't face any size problems in switching to a 225/55R17 tire for you Ford Ranger because the overall size is just a wee bit smaller than the original size. Since it is beyond the 2% limit I usually place on differences in sizes I would rather see you using a 225/60R17 which is almost the same size.

The one thing that you might find as an obstacle is the load range and speed ratings. You want to make sure that these both are at least the same, or even higher on the swapped tire when compared with the original. This way you will have no safety issues to worry about.

225/50/17 tires in place of 235/50/17 tires

by Joel
(Snellville,Ga,30039)

I have a 2001 Lincoln ls v6 with 17 factory Aluminum sport wheels. Recommended tire size is a 235/50/17 or a 245/45/17 tires. I have a set of Michelin that I would like to install but they are 225/50/17 tires. Can I use this size without affecting handling and performance.

Editorial Comment.

You wish to substitute a 225/50/R17 tire in place of a 235/50R17.

Because this is a narrower tire you will have no issues in terms of it fitting within the space available in your car. Since it is the same diameter wheel there will be no issues with interference to the operation of the brakes or anything else.

Since the tire is slightly smaller in overall volume (you're dropping from a width of 235 to 225) you will have to increase your air pressure slightly to maintain the operating radius of the mounted tires. This, for some people, at least gives them the sensation that their vehicle rides a bit more roughly than the original tire.

Apart from this issue I don't think you will face any other change which could be of great importance in the performance or safety of your vehicle. Just be sure that the speed and load rating of the new tire is the same or greater as what you have been used to using.

Mixing different sidewall aspect ratios in front and rear

by john
(belfast,maine)

can you pair up four tires with different sidewall aspect ratios ,like 215/55r/16 in front and 215/65r/16 in the rear

i have 2 tires that i want to put on the front of my 2002 ford windstar and the mini van calls for 215/65r/16 but the tires i have are 215/55r/16

Editorial Comment:

Take a look at the photo above and this will give you a very exaggerated graphic idea of what you are proposing (but in reverse)

You are thinking of using 215/55 R16 in the front and 215/60 R16 tires in the rear. The aspect ratio is used to calculate the height of the tire, so a higher ratio means a higher tire.

How much higher? Well, in your case the difference is 5, so the back tire will be 5% higher than the front one. 5% of what? 5 percent of the tire width, which is 215mm. That works out to be 10.75 mm, or just under 1/2 an inch, if you're not used to metric measurements.

The difference is not great, in absolute terms, but certainly the difference is enough to cause some variation in speedometer reading and fuel consumption. The actual size different is over 3% and this is more than I recommend people accept when they are changing all tires on a vehicle. If you are changing only 2 of the 4 the situation becomes more complicated because you need to consider what size tire you're going to carry as a spare, and always make certain that you keep the same sized tires on the same axle.

In short, I don't recommend that you do what you propose.

Tire Concerns: change from low profile tires to regular tires by using a smaller rim

by John
(Pittsburgh)

I have a 2011 Chevy Malibu with 18" low profile tires. Can I get tires with a higher profile by using smaller diameter rims?



Editorial Comment:

You certainly can do what you want. It is the same as what is commonly called Plus Sizing but in reverse. I guess you would call it "Minus Sizing."

The one thing you may find is that if you want to get a substantial difference in profile, you may wind up using a narrower tire than you now have and you may find some difference in the way the car feels as you drive it.

If you can find some way to try the new sized tire and see how it feels when you drive, I would suggest you do so before investing a lot into making the switch.

what size inner tube to use

by John
(KY)

i need a inner tube for a 205/75d14 tire and wondering what size it takes for the tube.

Comment:

Because inner tubes expand and contract with the air that in in them, you seldom need a specific size as long as the tube you choose is designed for the diameter tire you are using. So in your case you could use GR13/14/15 and get satisfactory results.

Optional tire sizes

by Anthony
(manchester ohio)

I have a 01 mitsubishi eclipse with 215 50r17 tires what other size will fit on that rim

Editorial Comment:

Your best bet for finding other tire sizes that are suitable for you Mitsubishi Eclipse, or any other vehicle is to use our Tire Size Calculator
Tire Size Calculator.

This will provide you with a range of sizes which fall within a pre-determined range of differences from your original tire. The default setting is 2%, which is what I normally recommend you stay within. If you are adventurous or wish to experiment you can go outside that limit but be prepared to accept the consequences.

The other thing to keep in mind is that each tire is designed to fit on rims of certain widths. Most tires have some degree of flexibility built into their design and that range is about 1 inch larger or smaller. In most cases you can either increase or decrease a tire width by about 1 inch (or 25 mm) and be fairly certain that it will fit on the rim you now have. Remember that tire widths like, 215 are in mm. So your range to stay within is from 190 up to 240.

This, of course is not considering the physical space in your vehicle's wheel wells, only what will fit on the rim. To determine if you have space, the best thing to do is to try a test fitting with a tire mounted and inflated and turning your steering wheel to the maximum on either side to make sure there is no conflict.

suitability of different sized tyres

by william ellis
(coleraine N.I.)

I damaged the front passenger side tyre wall. The size
was 235/55 R18. I was sold an excelent part worn tire to replace it until I eventualy replace the full set at the one time However the replacement is slightly different ie; 235/50 r18 and so I put it on the back drivers side.
I have moved the back drivers side wheel to the front passenger side in order that both front wheels are the same I have test driven the car and it drives very straight unlike before when there was a tendancy to pull to the left. Will this be okay.

Editorial Comment:

The 235/50 r18 tire is lower than the 235/55 r18 tire. Notice the second number which tells you the factor to use to calculate the tire height.

On the front a lower tire on one side will have the same effect as if you are driving with one tire which is low in air pressure, and it will cause the car to pull to one side. When you put the lower tire on the back there is still this same tendency but you don't notice it so much since it isn't transferred through the steering wheel.

Even though you don't feel it there is still an effect and it will result in your tires not wearing evenly, and could be a difference in traction on a slippery surface or if you need to stop or manoeuvre suddenly. For these reasons, we never like to see people use different sized tires on an axle … you put both tires the same on the rear,too. If you want, keep the odd sized tire as a spare and use it only for temporary emergencies.

best replacement tire size

by LOU
(TRUMBULL CT)

Would the tire size 235/65r/17 be a suitable size to replace original tire size 215/70r/17?- - Bridgestone Dueller is only tire for this size made for my car-OEM tire for my 2012 Mazda CX7. I cannot find a different tire maker for this size!

I need to consider an alternative- i am reading that the Bridgestone is not a long wearing tire- and not great in snow. my car currently has less than 5K miles and so far, the tires seem fine. I want to be proactive before winter arrives. the rims size is 17x7 width.

I am afraid the duellers will be poor in winter driving based on what I've read and learned AFTER buying the car -

Tire size 275/55r/17 seems to keep the same dimensions .02%, but you need a wider than 7 in rim to use these tires-right?

So I am thinking the 235/65r/17 .06% might be the best choice- at least I 'd have a few brands to choose from.

I correct in my thinking? any aid you can provide would help. thank you.


Editorial Comment

I you'll check out our Tire Size Calculator
Tire Size Calculator you'll find there are several alternative tire sizes which are within 2% or less of your original.

Indeed, the 235/65 R17 is one of the better choices because you're not likely to have any issues with wheel width. Most tires are designed to be used on a specific width of rim, but they will allow you to use rims that are from 1/2 to 1 inch wider or narrower. Since the difference between 215 mm and 235mm is 20mm, this is less than one inch, so these tires would not likely require a wider wheel.

The 275 tire is 60 mm wider and this is almost certainly going to require a wider rim. In addition you could find that they are too wide to even fit within your wheel well and operate without rubbing on something.

tire sizes

by joe
(chicago)

I have a 07 trailblazer with a tire size of 245 65 17 but I dont wana buy a new set winter tires because most of the time I have rims on it so my question is if I can put a different size tire and wat will be a better size for me to go

Editorial Comment:

There are several sizes that stay within the 2% size difference I recommend when considering changing tire sizes.

From smallest to largest they are:
235/65 17
255/60 17
225/70 17
265/60 17

The above are all smaller, later tires within my range limit are
235/70 17
275/60 17
255/65 17

This should give you to work on.

Tire Concerns: Increase one wheel by 1/2 inch width

I have a 05 Scion Xa. The wheel is 15x5.5

I'm looking for a full size spare but can't find this size rim (and same bolt pattern anywhere for a decent price)

I was able to find a 15x6 (scion XB) wheel that will fit the car.

3 questions:

1. Since I have to buy a full spare tire, can I use the same size as the others that are on the 15x5.5 wheel which is 185/60R15?

2. Will that extra 1/2 inch width on the spare wheel (when it is used) cause any problems with clearance or rubbing?

3. Assuming no issues with clearance, will the ride feel rough or different because (assuming the same size tire), it is stretched out another 1/2 inch on the larger wheel, so its overall diameter may be less?


Editorial Comment:

Most tires are made to be used on a certain recommended rim width, but almost always they may be used on "permitted" rims which are usually 1/2 inch wider to 1/2 narrower than the recommended size.

Check out our listing of Rim and Tire Sizes and see what shows up for your tire to be sure.

As for the issue of rubbing and clearance, the best thing is to try a test fitting to see how things work out on your vehicle. It is not always certain that a change will work, even if you know someone else with the same make and model because if your vehicle has suffered any damage or had any mechanical adjustments, that could be enough to upset things for you.

Wrong size tires on my impala

by Michael Mohrle
(clifton,nj,usa)

I bought a 2005 impala base 3.4 in April. I noticed the tires looked smaller than my friends 02 impala. They are 225/50r16 and should be 225/60r16. Is this ok? Why would the owner have put these tires on the car?

Will this size tire be ok?

At the moment I have 235 60R17 Tires on my 2006 Chevy Colorado. Will 215 65R17 be ok on it as well. There are some winter tires I want to go look at and I want to know if this size will work.

Editorial Comment

You may or may not have been aware of it, but in these choices of sizes (235 60R17 and 215 65R17) you have applied the classic rule of thumb for changing tire sizes: that is, when you increase one of the numbers you should decrease the other -- and vice versa.

So by decreasing the width from 235 mm to 215, you have increased the aspect ration from 60 to 65. The effect of this is to make the change in over all tire diameter practically nothing, which minimizes the effects on fuel economy and speedometer error.

This is a good swap.

Different profile tire

by Paul
(Burlington, Ontario, Canada)

I had 225/55/R16 winter tires on my 2003 Mustang. I traded in my Mustang and still have the winter tires. Can I put them on my 2010 Dodge Caravan? The All Season tires on the Caravan are 225/65/R16.

From my understanding, the only difference is the profile height of the tires, but the diameter and width are the same.

The winter tires have about 30,000km's on them and still have deep treads.

I'd like to use them on the van, or otherwise, I will sell them.

Comment:

If you'll check out the two tires using our Tire Size Calculator you'll see that there is a difference in tire diameter (not rim diameter), too. The 225/65 tires are larger by 10% of 225, or 22.5mm. This is almost 1 inch and that much difference might cause a clearance issue in vehicles where there isn't a great amount of excess space in the wheel well.

Try a test fitting and consider the other differences which the calculator shows you to see if this is OK for you.

Tire concerns: Using different size front to back

by Rob
(Fredericton, Canada)

I have a 2004 Honda Odyssey that I am looking to get some new tires on this winter. Just today I was in getting an oil change at my mechanic's garage and I noticed a couple of good tires up on a rack. It turned out they were GY UltraGrips 215/60/16 and are almost untouched. He will let them go for basically nothing as they came off a junked car.

Now here is my concern. Curently I am running FR710 225/60/16. I was wondering if there is any problem with running the winter tires 215/60/16 on the front and the all season 225/60/16 on the rear for the winter, then changing them out again in the spring back to the FR710 225/60/16 for the warmer driving season.



Editorial Comment:

I hope you are aware that the tires you are considering putting on the front are a lower profile than the ones on the back meaning that you'll be going downhill all the time. This could be great for gas mileage but horrible if you're trying to stop in slippery conditions!

Of course, I'm kidding. But not about the tires being lower in height. There is a slight difference of about 6mm, which isn't really a major concern.

The important thing is to not attempt to rotate your tires or mix different sizes on the same axle. If you follow this, since the vehicle is not 4WD, you shouldn't have any major issues.

Tire Concerns: Switching sizes on Dodge Ram pickup

My 2003 Dodge Ram pickup currently has 275/60R20 tires on stock rims. Can I replace this with new 17 inch rims and 295/70R17 tires? It looks like the resulting overall size will be less that 1% bigger.

Part B of the question is can I retain one of the old tires/rims as a spare, or do I need to buy 5 new tires/rims?

Editorial Comment.

It would appear that you have used a Tire Size Calculator to compare the two different sizes and have determined that there is little difference in the outside diameter of the two tires.

This is good, however, there still is one other consideration which needs to be looked at: Will 17 inch wheels function on you Dodge Ram. It seems that some models of Ram pickups did come with optional 17 inch wheels, so there seems to be a reasonable chance that you may be OK, but you want to make sure that there will be no interference with the brakes or suspension because of the smaller wheel.

As far as keeping one wheel a different size for a spare, you know that for awhile it was common for cars to be equipped with spare tires which had a special size. Certainly it is possible, but you may find in practice that there are some drawbacks to having one odd wheel … rotation becomes cumbersome and you won't be able to swap one tire on to the other rim if some circumstance arises to create the need.

In the long run I think you'd be happier if all were the same size.

shorter tires going to affect abs or trans on 08 f350 powerstroke?

by adam
(il)

i have 275 65 20s on truck. very expensive tires. can i go 275 60 20 without hurting anything besides racking up more miles than actual?

Editorial Comment:

There's about a 3% difference in the diameter and fuel consumption in switching to a 275/60 tire. It may fit because there is only about 1/2 inch difference in the sidewall height but you will want to figure out if a 3% extra cost in fuel over the life of the tires is enough to make up the difference.

The speedometer will show the same 3% error difference and because it will show less than your real speed, will you possible have an increased risk of getting a speeding ticket (adding to your costs) during the life of the tires? You know your driving habits, I don't … is this an added risk for you?

The only way to know for sure if these tires will fit is to try a test fitting and closely inspect the clearance that you have. Don't rely on what other's might say … your vehicle may be different.

What size tires should I use with the new rims I just bought?

by jen
(milwaukee, wi)

I bought a new set of rims for my Bravada and the box came marked with the numbers 5 x 120.65 and 16 x 8....

what do the numbers mean and what size tires should i get? I know 16" but what does the 8 mean?

Editorial Comment:

The numbers on your rims refer to the bolt pattern and the tire sizes.

The 5 x 120.65 means that there are 5 bolt holes which are spaced 120.65mm between each one.

The 16 x 8 refers to the tire to be used on the rims. 16, as you seem to have already concluded is the size of the tire rim as in the last number in 225/65/R16. The 8 means that the rim is 8 inches wide and there are certain tires which can be used on that width of rim.

Look at Rim and Tire Sizes and find the 16 inch rim diameter and then locate the 8 inch width to see the tires that recommend this sized rim. Usually most tires are also permitted to be used on rims which are either 1/2 inch narrower or wider, but not more. So you can also use the tire widths which are recommended for 7.5 or 8.5 inch rims, also.

swapping tire size

by mike
(buffalo ny)

can I use 235 60 R16 in place of 225 75 R16?

Editorial Comment

You are on the right track in these tire sizes, but your values are too far out of a comfortable range. The idea is to increase one of the numbers when you decrease another number. Usually you move to the next "standard" step to maintain the same overall diameter.

So from 225/ 75 R16 you would go to 235/70 then check your numbers. This would be a difference that says within the 2% range which we recommend. Other possibilities would be 245/70 16 or 255/65 16. Of course you need to be certain that the added width will look ok and will fit within the space available.
